Should I Keep My Car or Buy New? Repair Costs vs a New Payment

If your car runs well and is paid off, keeping it is almost always cheaper than buying new. In our worked example below, keeping a 2016 Honda Civic with 108,000 miles costs about $9,600 over two years, including repairs, while a new compact sedan costs about $23,600 over the same two years.

Replacing starts to make more sense when a single repair would cost more than half of what the car is worth, when major repairs stack up, or when the car is no longer reliable enough for work and family. This guide shows how to run the numbers for your own car, and whether to keep paying, refinance, lease or replace a high-mileage car.

The True Cost of Car Ownership 2026: Complete Maintenance & Money-Saving Guide

Quick Answer: Keep It, Fix It or Replace It?

Wanting a new car is normal, and so is feeling attached to the one you have. Set both feelings aside for a minute and check where your car sits in this table.

How to Compare Repair Costs With a New Car Payment

Let's establish the baseline. When deciding whether to keep or replace your car, you need to compare the total cost of ownership over a specific time period (typically the next 2 to 3 years, or until your car would likely need a major repair).

To compare fairly, add up what each option costs over the same two years: repairs and maintenance, insurance, registration and taxes, fuel and, for a new car, the down payment and loan payments.

What It Costs to Keep Your Current Car

Expected Repairs & Maintenance

This is where a lot of people stumble. You can't just use your historical average because cars tend to need bigger repairs as they age. Once you hit 100,000 to 150,000 miles, the probability of major repairs accelerates.

For more, see our guide on 100,000 miles and major repairs.

Look at your maintenance records from the past year. Did you have any major repairs? Check databases like repairpal.com or ask your mechanic to estimate likely repairs for the next 2 to 3 years. For cars over 120,000 miles, budget conservatively. If you're not sure, add 30 to 50% buffer to your estimates. For a used car, repair bills usually grow with every year you own it; our guide to the real cost of owning a used car shows typical costs by year.

Insurance & Registration

Here's a minor win for older cars: insurance premiums are typically lower. But registration fees vary wildly by state. Some states charge less for older vehicles. Factor in what you're currently paying, then adjust slightly (insurance might drop $20 to $40/month if you have an older car compared to a new one, but this varies).

Fuel & Other Operating Costs

Older cars typically have worse fuel economy. If your 10-year-old SUV gets 22 MPG and you're comparing it to a new hybrid getting 45 MPG, calculate the difference. At current gas prices (April 2026), this could save you $100 to $200/month depending on driving habits.

Let's Build a Real Example:

Sarah owns a 2016 Honda Civic with 108,000 miles. It's generally reliable but just failed inspection: the brake pads are worn and the mechanic mentioned the transmission fluid is getting dark.

What It Costs to Buy New

This is where many people's eyes glaze over, because new car costs are more psychologically complicated than repair costs.

Down Payment

New cars in 2026 run anywhere from $25,000 (base model sedans) to $60,000+ (SUVs, crossovers, or specialty vehicles). Let's assume Sarah is looking at a mid-range new Honda Civic or Toyota Corolla: roughly $28,000.

If she finances 90% with a $2,800 down payment:

• Amount financed: $25,200
• At 6.5% APR for 60 months: $493/month

Over 24 months, just the car payment is $11,832. Add the down payment, and you're at $14,632 before insurance, registration, and fuel.

Registration & Sales Tax

Sales tax varies by state (typically 5 to 10%), and registration for a new car is higher. Budget $2,000 to $3,000 for your first year.

Insurance for a New Car

Comprehensive and collision coverage on a new car costs more: roughly $1,500 to $2,000/year, or about $25 to $67/month more than her current situation.

Fuel

New cars are more efficient. If Sarah gets a new Civic with 32 MPG instead of her current 28 MPG, she saves about $250 a year in gas at the same fuel price.

Two-Year Cost: Keeping a 2016 Civic vs Buying New

Here are Sarah's two options side by side, using the figures above: 12,000 miles a year, a new car of about $28,000 financed over 60 months at 6.5% APR.

Keeping the Civic costs about $14,000 less over two years. Even if Sarah's repairs ran $3,000 to $5,000 higher than planned, keeping the car would still cost less.

This is cash out of pocket. After two years the new car still has resale value, so part of the gap comes back when you sell. Most of it does not: interest, sales tax, higher insurance and the first years of depreciation are gone for good. The math only favors keeping the car while it stays reliable and no very large repair hits, which is what the next section covers.

When Replacing Your Car Makes More Sense

Keeping your car stops being the cheaper choice in these five situations.

Major Repairs Start Stacking Up

Vehicles in the 120,000 to 180,000 mile range start hitting the wall. Common expensive failures include:

• Transmission replacement: $1,500 to $8,000 or more
• Engine replacement: $3,000 to $7,000 or more
• Suspension/steering: $1,000 to $3,000 or more
• Electrical system: $500 to $3,000 or more

If your mechanic is recommending multiple major repairs simultaneously, the old car advantage shrinks fast. When you're looking at, say, a transmission replacement ($3,500), timing belt replacement ($800), and water pump repair ($400), you're suddenly at a $4,700 repair bill. Combined with other aging components needing attention, the total cost picture changes.

A simple rule: if one repair would cost more than half of what the car is worth, put that money toward a replacement instead. Check your car's value before you approve a big repair.

Your Car Is No Longer Reliable

There's a hidden cost to an unreliable car that spreadsheets don't capture: life quality and opportunity cost.

If your car leaves you stranded twice a year, if you can't trust it for a road trip, if every time you hear a new noise your stomach drops, you're paying in stress. You might miss important meetings, be late to pick up your kids from school, or cancel plans because you're worried about reliability.

Some people have a high tolerance for this. Others don't. Both are valid.

Additionally, if you rely on your car for work or have a long commute, reliability becomes non-negotiable. A delivery driver, rideshare driver, or salesperson whose car frequently breaks down faces actual lost income.

You Need Coverage Just to Keep the Car Running

Repair coverage on an older car is a good way to turn a surprise repair bill into a fixed monthly cost. It is not a fix for a car that is already failing. Problems that exist before coverage starts are not covered, so a plan cannot rescue a car that needs a transmission today.

If the only way you can afford to keep your car is to cover it against every possible failure, compare that monthly cost with a new car payment. Coverage should support a decision to keep a sound car, not be the reason you keep a bad one. Our guide to extended warranties for high-mileage cars explains what these plans cover after 100,000 miles.

Your Model Has Known Expensive Failures

Certain vehicles develop patterns of expensive failures. The Honda Odyssey with transmission problems. The Ford Focus with dual-clutch transmission issues. The Jeep Grand Cherokee with electrical gremlins.

If you've got a car that's notorious for specific expensive repairs, and you're approaching that mileage range, the math shifts.

For more, see our guide on Honda and Toyota reliability comparison.

Similarly, if you own an increasingly rare model or one with hard-to-find parts, repair costs can spike 20 to 30% above normal vehicles.

Fuel Costs Are Eating Your Budget

If fuel prices jump significantly from 2026 levels, or if you're driving an old SUV or truck with poor fuel economy, the fuel cost difference between a new efficient vehicle and your current car becomes more meaningful. An extra $200 to $300/month in fuel adds up.

Mileage, Brand, Maintenance and Budget: What Else to Weigh

Okay, the math might favor keeping your car. But numbers don't exist in a vacuum. Here's how to think about the practical, non-financial factors:

How Many Miles Is Too Many?

Most drivers put about 12,000 to 15,000 miles a year on a car, according to EPA estimates, so a car with 100,000 miles is usually 6 to 8 years old. That is not old for a modern car: the average car on American roads is 12.6 years old, and well-maintained cars often run 15 years and past 200,000 miles. See how long cars really last for what tends to break at each milestone.

Cars under 80,000 miles: Usually a good bet to keep. Even with maintenance, you're probably 5 to 7 years away from needing to make this decision again.

Cars between 80,000 and 120,000 miles: The sweet spot for keeping. You'll likely get another 3 to 5 solid years with routine maintenance. Major repairs become possible but not inevitable.

Cars over 120,000 miles with good maintenance records: Still viable, especially if they're reliable models. But you should have an emergency fund of at least $3,000 to $5,000 set aside.

Cars over 150,000 miles: Still worth keeping if the car is reliable, but get a quote before every major repair and compare it with the car's value.

Brand and Model Reliability

Toyota, Honda, and Lexus vehicles are notoriously reliable and hold up well past 150,000 miles. If you own one of these and the maintenance history is solid, the case for keeping is very strong.

Brands with higher failure rates in the 100,000 to 150,000 mile range (certain Ford, Chrysler, and Jeep models are notorious) weaken the 'keep it' argument.

Check your model's track record in our vehicle reliability hub or on Edmunds before you decide.

Your Actual Maintenance History

A car with regular maintenance records = a car likely to keep running. You're essentially pre-paid for longevity.

A car with spotty maintenance = a time bomb. You might've saved money skipping oil changes, but you're about to pay for it in major repairs.

If you've neglected maintenance, frankly, you need to ask yourself whether you'll do better with a new car (spoiler: you probably should, because accountability matters).

How Much You Drive

If you drive fewer than 8,000 miles per year, your car will age slowly. You could reasonably keep it another 5 to 10 years.

If you drive 20,000+ miles annually, mileage accumulates quickly: you might need to make this decision sooner.

Your Financial Situation

This matters more than any calculation.

• Have a healthy emergency fund ($10,000+)
• Can comfortably afford a $3,000 to $5,000 surprise repair without stress
• Are not stretched financially

...then keeping your car is the smart move financially.

If you:

• Are living paycheck to paycheck
• Would struggle with a $1,500 unexpected repair
• Don't have a safety net

...then maybe the peace of mind of a reliable new car with a warranty is worth the financial cost. Your mental health and financial stability matter. Not sure whether a repair fund or a protection plan fits you better? Compare both in extended warranty vs emergency fund.

High-Mileage Car Loans: Keep Paying, Refinance, Lease or Replace?

Many owners are not choosing between an old car and a new one. They are still paying for the old one. Here is how to think about the loan side of the decision.

What Lenders Look at on a High-Mileage Car

Lenders look at the car's age, its mileage, what it is worth compared with the loan balance, and your credit. Each lender sets its own age and mileage limits for car loans and refinancing, so a car that one lender turns down may be fine with another. Ask your bank or credit union for its limits before you apply.

Refinance or Keep Paying?

Refinancing makes sense when you can get a clearly lower rate and you plan to keep the car longer than the new loan runs. Do not stretch a loan past the years the car has left: paying for a car and repairing it at the same time is the most expensive way to own one. If you owe more than the car is worth, keep paying it down rather than rolling the balance into a new car loan.

Is a Lease Smart if You Drive a Lot?

Usually not. A lease comes with a yearly mileage limit and a charge for every mile over it, and drivers who cover far more than the usual 12,000 to 15,000 miles a year pay for that at the end. If you drive a lot, buying a reliable car and keeping it for many years usually costs less.

Questions to Ask Before You Decide

Answer these five questions honestly before you sign anything.

1. Step 1: Run your numbers honestly. Use the framework above. Get repair estimates from a trusted mechanic. Don't guess.
2. Step 2: Assess reliability honestly. Is your car genuinely failing, or is it just aging? There's a difference.
3. Step 3: Evaluate your capacity for inconvenience. Can you handle occasional repairs and rare inconvenience? Or do you need the security of knowing your car will reliably get you where you need to go?
4. Step 4: Look at your cash flow. Can you afford to keep maintaining your current car? Can you afford a $400 to $500/month new car payment?
5. Step 5: Make peace with your decision. Once you've decided, commit to it. If you're keeping your car, embrace it and don't second-guess yourself. If you're buying new, enjoy the fresh start and don't regret the expense.

Keeping an Older Car? How to Cap Big Repair Bills

Keeping your car only pays off while repairs stay manageable. One surprise $5,000 transmission bill can wipe out two years of savings. You have two ways to protect against that.

• A repair fund. Set aside $3,000 to $5,000 in a separate account. This works best if your car is reliable, you drive less than average and you would not need to borrow to pay a big bill.
• Repair coverage. A vehicle service contract, often called an extended car warranty, pays for covered breakdowns so a big repair does not land on your credit card. This works best if a large bill would hurt your budget or your car is past its factory warranty.

With CoverageX, you choose from four plans: Essential covers the engine, transmission and drivetrain; Signature adds electrical systems, air conditioning and suspension; Premium covers nearly all mechanical and technology systems; Executive covers everything except a short list of exclusions. Coverage starts 30 days and 1,000 miles after purchase, and problems that existed before that are not covered. When a covered part fails, you pay your deductible to the shop, CoverageX pays the shop directly, and your monthly rate is locked for the life of the contract. Maintenance, wear items such as brake pads and tires, and accident damage are not covered on any plan.

Coverage is not worth it for everyone. If your car is very reliable, you drive little and you have savings to cover a big repair, the repair fund is often the better deal; see when not to buy an extended warranty.

Keep or Replace: The Short Checklist

Use this checklist if you are still on the fence.

Keep your car if:

• It's under 150,000 miles with good maintenance history
• No major repairs have failed recently
• You can afford a $2,000 to $5,000 emergency repair
• You value financial savings over new car peace of mind
• You can handle the occasional inconvenience of repairs

Buy a new car if:

• You're facing $400+ monthly in repairs
• Your car has become unreliable enough to affect your life
• Your car has passed 200,000 miles and a major repair would cost more than half its value
• Peace of mind and reliability are worth more to you than the financial cost
• Your current car is a known lemon with pattern failures
• Major repairs are piling up, such as transmission and engine problems at the same time

The hybrid approach if you're uncertain:

• Commit to keeping your car for one more year
• Fund a dedicated repair emergency account ($3,000 to $5,000)
• Consider an extended warranty to cap your risk
• Reassess in 12 months with actual data from that year

Most people, when they run the real numbers, discover that keeping their car is the financially smarter move. But 'financially smart' isn't the only kind of smart. If a new car makes you happier, less stressed, and more confident in your transportation, that's worth something too.

The Bottom Line

For more, see our guide on CoverageX auto protection plans.

The decision to keep your car or buy new isn't actually complicated. It's just not simple.

The math usually favors keeping, sometimes by a lot. But the math doesn't know if you have anxiety about your car breaking down, if you're about to take a major road trip with your family, or if you've just hit a point in your life where you deserve something new.

Run the numbers. Assess your situation honestly. Make a decision you can live with. And then commit to it instead of second-guessing yourself.

Your 2016 Honda Civic (or 2017 Toyota Corolla, or 2015 Ford Focus) probably has years of life left in it. Keeping it, with a realistic repair budget, can save you around $14,000 over two years compared with buying new.

But if you buy new anyway, that's valid too. Just make that choice consciously, not because you thought the math forced your hand.

Keep or Buy New: Frequently Asked Questions

Is it cheaper to keep an old car or buy a new one?

Keeping a reliable, paid-off car is almost always cheaper. In our example, keeping a 2016 Honda Civic costs about $9,600 over two years with repairs included, about $14,000 less than buying a new compact sedan. The gap closes only when big repairs pile up or one repair costs more than half the car's value.

How many miles is considered high mileage for a car?

Most people treat 100,000 miles as high mileage. Drivers put about 12,000 to 15,000 miles a year on a car, so that is usually a 6 to 8 year old car. Many well-maintained cars run well past 200,000 miles; see what to expect from a car with 100,000 miles.

Is it okay to keep driving a car with 200,000 miles?

Yes, if it has been maintained and still runs reliably. Many models, such as the Toyota Corolla and Camry, regularly pass 200,000 miles. Get a mechanic to check it once a year and decide on any major repair by comparing its cost with the car's value.

When is a car not worth fixing anymore?

A car is usually not worth fixing when one repair would cost more than half of what the car is worth, or when several major repairs are due at once. A transmission replacement can cost $8,000 or more, so check the car's value before you approve the work.

Can you refinance a car with 150,000 miles?

Sometimes. Each lender sets its own age and mileage limits, so ask your bank or credit union before you apply. Refinance only if the new rate is clearly lower and the new loan ends before the car is likely to need major repairs.

Is leasing a good idea for a high-mileage driver?

Usually not. Leases have a yearly mileage limit and charge for every mile over it, so drivers who cover far more than 12,000 to 15,000 miles a year often pay a lot at the end. Buying a reliable car and keeping it longer usually costs less.

Should I replace an old car instead of refinancing it?

Replace it if the car needs major repairs soon or has become unreliable, because a lower payment does not help if repair bills keep coming. Refinance or keep paying if the car is sound and you plan to keep it longer than the loan runs.

How long do most people keep a car?

Many people keep cars well beyond the loan: the average car on American roads is 12.6 years old. If you plan to sell, the best time is usually between 120,000 and 160,000 miles, before the most expensive age-related repairs. See how long cars really last.

Is an extended warranty worth it on a car I plan to keep?

It can be if a large repair bill would strain your budget and the car is past its factory warranty. A vehicle service contract from CoverageX pays the shop directly for covered repairs after a 30-day and 1,000-mile waiting period, but it does not cover problems that already exist or routine maintenance. If you have savings and a very reliable car, a repair fund may be enough; compare CoverageX auto protection plans.
