The bottom line: A car with a major mechanical problem is best sold to one of the few instant car buyers that specialize in it. They come to you, tow it for free and pay you the same day.
The usual options close off fast. Dealers pass, and private buyers get nervous when they hear “check engine light” or “won’t start.” Most online buyers built for clean, running cars won’t even give a quote.
We tested Peddle, Wheelzy and CashForCars across five vehicles. CarBrain is another buyer to try, and eBay Motors and Facebook Marketplace let you sell it yourself.
Some buyers ask about the problem in the quote form and price it in. Others quote online and have the driver check the car at pickup. Most quotes are fast, though some high-value cars need a phone call to finalize the offer.
The winner changed with the vehicle, so get quotes from 2 to 3 buyers to find who offers the most for your car.

Key Takeaways
- Who buys it: Peddle and CashForCars priced all five of our cars with mechanical faults online and Wheelzy four of them, while dealers pass and Carvana won’t take a car it can’t drive safely, so skip the dealer’s lot and get the online offers.
- What buyers offered: Buyers offered $345 to $501 for four of our cars with mechanical faults, 2003 to 2010 with 99,000 to 240,647 miles, and $1,100 for a 2005 Sequoia, so expect a few hundred, more for a full-size SUV.
- Who offered most: Wheelzy led by $31 to $103 on four of the five cars and Peddle by $476 on the 2005 Sequoia, so start with Wheelzy and add Peddle on a pricier car.
- On the quote form: Answer each form exactly, and on Peddle’s a check engine light alone still counts as starts and drives, while a misfire, a leak or overheating means starts but doesn’t drive.
- Selling it yourself: Facebook Marketplace can bring much more for a fault a backyard mechanic can fix, though buyers will haggle over it, so list that kind there and let an instant buyer tow a car that won’t run.

Our take on Peddle: Peddle is built for cars that private buyers won’t touch, including vehicles with blown engines, failed transmissions, and other mechanical issues. They gave an instant online quote for all five cars we tested and stood out on the 2005 Toyota Sequoia, where their offer was far above anything else we received. You get up to seven days to accept, which leaves time to check competitors first.
Pros
- Gave instant online quotes for all 5 vehicles with mechanical problems, no phone call needed
- Free towing whether your car runs or won’t start at all
- Up to seven days to accept the offer
Cons
- The driver may lower the offer at pickup if the mechanical issue turns out to be worse than described
- Pickup windows are 4-hour blocks, not a specific arrival time
- Offers are lower than what you’d get fixing the car first and selling privately
Why we picked it: Peddle was the most reliable instant buyer for cars with mechanical problems in our test. They gave immediate online quotes for every vehicle, including two cars with over 200,000 miles and active mechanical failures. Their offer on the 2005 Sequoia ($1,100) was nearly double the next-highest quote. For sellers who want a fast, no-call process, Peddle is the most consistent option.
Best For Highest Instant Offers: Wheelzy
Wheelzy buys cars in any condition, running or not
- Buys cars without keys
- Buys cars missing parts, engine and transmission in
- Pays cash or check at pickup
- Quote often needs a phone call

Our take on Wheelzy: Wheelzy targets cars that most buyers won’t touch, including vehicles with blown engines, bad transmissions, and collision damage. They came back with the highest offer on all 4 vehicles where they gave an instant quote. The driver checks the car at pickup against what you described, and the offer can drop if a part like the catalytic converter is missing or replaced, so describe the car exactly.
Pros
- Offered the highest instant quote on most of the vehicles with mechanical issues we tested
- Price holds at pickup for a major mechanical failure you described, as long as no original part is missing
- Free towing for cars with mechanical problems that can’t be driven off the property
Cons
- Higher-value vehicles with mechanical issues may require a phone call instead of an instant online quote
- Independent tow contractors handle pickups, so the experience can vary by area
- They don’t buy vehicles older than 1981
Why we picked it: Wheelzy came back with the highest offer on the 2003 BMW X5, 2006 Pontiac G6, and 2008 Audi A6 in our mechanical-problems test. Their online quote process is fast and they specialize in damaged and non-running vehicles. For most cars with mechanical issues, they’re a strong first stop for a quote. Just note that for larger vehicles, they may ask you to call to get a firm price.
Best For Auction-Backed Pricing: CashForCars
CashForCars is owned by Copart and buys cars in any condition
- Free towing from nearly 200 locations
- Buys any vehicle with a motor, running or not
- Backed by Copart auction yards
- Pays a check right at pickup
-

Our take on CashForCars: CashForCars is owned by Copart, the largest auto auction network in the country. That backing gives them established routes to buy and resell mechanically damaged vehicles at scale. They ask about mechanical issues directly in the online quote form, so the problem is priced in from the start, though the offer can still change at pickup. They gave instant quotes for all five cars in our test and had the second-highest offer on most vehicles.
Pros
- Mechanical issues are factored into the online quote so there are fewer surprise price changes for problems you already disclosed
- Copart backing means around 200 locations and broad resale channels for cars with all types of mechanical damage
- Gave instant online quotes for all 5 vehicles, including cars with significant mileage and active mechanical failures
Cons
- Payment is by check, and the time before you can access the funds isn’t fixed
- Expect follow-up calls and emails after submitting a quote for a car with mechanical problems
- Won’t buy if you still owe money on the car, regardless of its mechanical condition
Why we picked it: CashForCars stands out because they build the mechanical issue into the quote before you ever get a number. Their Copart network gives them an edge in pricing cars with mechanical damage because they know exactly where those vehicles will end up. They were the only service alongside Peddle to give instant quotes on every car in our test, making them the most complete alternative if Peddle’s offer comes in low.
Best For Negotiating Your Price: CarBrain
CarBrain specializes in wrecked and broken-down vehicles
- Pickup 24 to 48 hours after accepting
- Buys totaled and wrecked cars
- Buys cars with blown engines
- Handles bad transmission sales

Our take on CarBrain: CarBrain has been buying problem cars since 2007 and puts its offer count near one million. For mechanical issues, it helps that CarBrain’s form let us counter its first offer. If you feel the online form didn’t capture the full picture of your car’s condition, you can push back. They won’t buy a car if the engine or transmission has been completely removed, even if other mechanical parts are present.
Pros
- Lets you counter the first offer, giving you a real shot at more money when a mechanical problem is hard to describe accurately online
- Free towing even if the mechanical failure makes the car completely immovable
- Handles cars with salvage titles and accident history alongside mechanical problems
Cons
- Won’t buy a car if the engine or transmission has been fully removed, even if the rest of the car is intact
- Offers tend to run lower than some competitors for the same mechanically troubled vehicle
- Expect follow-up calls and emails after submitting a quote request
Why we picked it: The counteroffer option is what earns CarBrain a spot here. Mechanical problems cover a wide range of severity, and an online form doesn’t always capture the nuance. Having the ability to negotiate means you’re not locked into the first number, which is especially valuable when your mechanical issue sits somewhere between minor and severe. Free towing is always included and there are no fees at any point in the process.
Other Options For Selling a Car With Mechanical Problems
If you’re willing to do the work yourself, listing platforms can get you more money than an instant buyer. The trade-off is that you handle all buyer questions, inspection logistics, and paperwork on your own.
Carvana is out if the fault stops the car driving safely, because it checks that at the appointment before it takes the car.
Best For National Auction Reach: eBay Motors
eBay Motors lists your car to buyers nationwide
- Listing fee is $34 or $79
- 40 photos with either fee
- No percent fee on sale price
- 2.8% fee on deposits via eBay
-
Buyer reach 25% 3/5
-
Safety features 25% 4/5
-
Listing cost 20% 3/5
-
Time to sell 15% 4/5
-
Ease of listing 15% 3/5
Our take on eBay Motors: eBay Motors is a listing platform that reaches buyers nationwide. For cars with mechanical problems, the auction format can work well because the right buyer, a mechanic, parts reseller, or DIY hobbyist, will often pay more than an instant buyer simply because they know what the repair actually costs. A listing costs $34, or $79 if you price the car over $15,000, with no percentage taken from the sale.
The catch is you do everything yourself. You describe the mechanical issue accurately, answer buyer questions, and coordinate pickup for a car that may not run. For vehicles with parts value and a loyal following (luxury models, trucks, popular imports), eBay Motors can be worth the extra effort.
Best For Local Free Listings: Facebook Marketplace
With Facebook Marketplace you sell your car directly to local buyers
- Sell directly to local buyers
- Chat through the platform only
- Post in local buy/sell groups
-
Buyer reach 25% 5/5
-
Safety features 25% 3/5
-
Listing cost 20% 5/5
-
Time to sell 15% 4/5
-
Ease of listing 15% 5/5
Our take on Facebook Marketplace: Facebook Marketplace is free to list and reaches local buyers right away. For cars with mechanical problems, it works best when you’re transparent about the issue and can find a local mechanic or project car buyer who knows what the fix is worth. Setting up your listing takes about 15 minutes and you keep full control over the price.
Be ready for buyers who will try to use the mechanical issue to push the price down hard. You’ll also need to sort out pickup logistics for a car that may not drive. If the problem is something a backyard mechanic can tackle easily, you may get a lot more money here than from an instant buyer.

Selling Cars With Mechanical Problems: What Each Buyer Offered
We submitted 5 vehicles with mechanical issues to Peddle, Wheelzy, and CashForCars using the same Florida zip code. Every car had active mechanical problems and high mileage at the time of quoting.

We got these quotes with a Florida ZIP code. Your offers can be higher or lower, because they depend on where you live, your car’s condition and what buyers need in your area.
What This Tells Us
What this tells us:
- The gap between the highest and lowest offer is narrow on lower-value vehicles with mechanical issues but grows on higher-value models, which means getting multiple quotes matters more the more your car is worth.
- Buyers with large auction networks have established channels to resell mechanically damaged vehicles, which is why their pricing tends to be more consistent across different vehicle makes and conditions.
- When a service asks you to call instead of giving an instant quote, it usually means the vehicle sits at the edge of their automated pricing model, often because of the combination of the make, mileage, and mechanical issue.
- Cars with mechanical problems that still have their major components physically present get better offers than vehicles where the engine or transmission has been removed, even partially.
- For less severe mechanical problems (dead battery, bad alternator), getting a repair estimate first makes sense. If the fix costs less than the gap between a mechanical-problems offer and a running-car offer, fixing it can pay off and opens up more buyers.
- Describing the mechanical problem accurately upfront cuts down the chance of an offer change at pickup, since drivers will test or inspect problem cars before loading them.
- Luxury and imported vehicles with mechanical problems tend to show wider offer spreads, likely because buyers assess parts value differently based on make and model.
- Getting quotes from all three instant buyers takes about 10 minutes and often reveals a meaningful gap, especially on vehicles that are harder to price with an automated system.
Both sides of the repair-or-sell test have a figure. National averages from RepairPal put an alternator at $809 to $1,088, against $6,238 to $6,764 for a transmission, with parts at the manufacturer’s list price. In our offer data, a car that does not start is offered about 46% less than a comparable car that drives, and one with a dashboard warning light on about 18% less than one without.

Frequently Asked Questions
Should I fix the mechanical problem before selling?
It depends on what the repair costs. Minor issues like a dead battery or bad alternator may be worth fixing because the cost is low and fixing it opens up more buyers and better offers.
Major failures like a blown engine or seized transmission usually cost more to repair than they add in sale value.
Before you decide, get a repair estimate and compare it to the instant buyer quotes. Use RepairPal to get a sense of what the repair might cost in your area.
If the fix costs less than the gap between a mechanical-problems offer and a running-car offer, fixing it first is worth it.
How much does a mechanical problem reduce the value of a car?
It depends on the severity and the car. Minor problems that are cheap to fix reduce value less than a blown engine or failed transmission.
Instant buyers price mechanical issues based on what it will cost them to repair or part out the vehicle.
Luxury and imported cars with mechanical problems can hold more parts value, which sometimes results in better offers than you’d expect given the condition.
Can I sell a car with mechanical problems privately?
Yes, but the buyer pool shrinks fast. Most private buyers want a car they can drive away.
A car with a mechanical issue attracts mostly mechanics, DIY enthusiasts, and parts buyers, all of whom will negotiate harder once they know what the repair costs.
If you go the private route, be fully transparent about the mechanical issue in your listing and price it to reflect that.
Facebook Marketplace and eBay Motors both attract buyers who specifically look for project cars and fixer-uppers.
Do I have to disclose mechanical problems when selling my car?
Yes. Most states don’t make you volunteer a known mechanical problem, but you can’t lie about it when a buyer asks. Giving a false answer about a mechanical issue in a private sale can expose you to legal liability after the transaction closes.
For instant buyers like Peddle, Wheelzy, and CashForCars, disclosing the problem accurately also protects your quoted price, though Peddle can still cut it if a flat battery stops the driver reading the mileage. If the driver discovers an undisclosed issue at pickup, the offer can change on the spot.
How fast can I sell a car with mechanical problems?
Instant buyers like Peddle, Wheelzy, and CashForCars can have your car picked up within 24 to 48 hours of accepting an offer. Same-day pickup is possible in some areas.
Selling privately through Facebook Marketplace or eBay Motors takes longer.
Expect up to 8 weeks or more for a car with mechanical issues, since fewer buyers want one and each will want to inspect it before committing.
What do I need to sell a car with mechanical problems?
For instant buyers, you need the title in your name and a valid photo ID. Peddle and CashForCars need it free of any active loan or lease, while CarBrain can pay off a loan when its offer is $1,000 or more and covers the balance.
Remove your personal items, take off the license plates unless you’re in Alaska, California, Hawaii or Minnesota, and make sure a tow truck can reach the car.
For a private sale, gather any maintenance records and be ready to describe the mechanical issue in detail. Serious buyers will ask specific questions about what’s wrong and whether anything has been done to try to fix it.
Methodology
We selected 5 vehicles that all had active mechanical issues at the time of quoting: a 2003 BMW X5 3.0i (240,647 miles), a 2005 Toyota Sequoia Limited (239,736 miles), a 2006 Pontiac G6 Sedan SE1 (99,000 miles), a 2008 Audi A6 Sedan 3.2 Quattro (196,000 miles), and a 2010 Chrysler Town & Country Touring (149,581 miles).
We submitted each vehicle to Peddle, Wheelzy, and CashForCars using the same Florida zip code. We answered all questions honestly and selected “Yes” when asked about mechanical issues. We took screenshots of every result, including one instance where Wheelzy directed us to call rather than providing an online quote.
Peddle and CashForCars gave instant online quotes for all 5 vehicles. Wheelzy gave instant quotes for 4 out of 5 vehicles and required a phone call for the 2005 Toyota Sequoia Limited. CarBrain, eBay Motors, and Facebook Marketplace were included based on their features and are not part of the direct quote comparison.
We did not accept any offers. Your results may differ based on your location, your car’s exact condition, and which buyers are active in your area at the time you get quotes.
