The bottom line: A blown head gasket shuts most doors. Private buyers walk away the moment you mention it, and dealers won’t touch a car that might overheat on the test drive. The repair cost often exceeds what fixing it adds to the sale price. But a few online car buyers will still make you an offer without repairs.
Instant buyers price these cars on parts and scrap value, not what they’d be worth running. Marketplaces let you find a buyer directly and can get you more money, but you handle everything yourself.
The winner changed depending on the vehicle, so getting quotes from 2 to 3 buyers is the best way to find who offers the most for your car.
Our take on Wheelzy:Wheelzy specializes in cars with mechanical problems, including head gasket failures. They buy cars in any condition, whether the engine is leaking coolant, has overheated, or has completely seized. Their quote process takes about 2 minutes online, and they lock in your price at pickup as long as your car matches your description. Towing is free whether the car runs or not.
Pros
Offered the most in our test for cars where a head gasket failure made the vehicle non-drivable
Free towing even when a blown head gasket has left the car completely immovable in your driveway
Often willing to match or beat competitor offers if you show them a higher quote
Cons
Couldn’t give an instant online quote for one of our 5 test vehicles and required a phone call instead
Offer may change at pickup if the head gasket damage caused coolant contamination you didn’t mention
Why we picked it: On the 4 vehicles where Wheelzy gave an instant quote, they came out on top every single time. The Toyota Camry with 228,776 miles got $466 from Wheelzy versus $424 from CashForCars and $380 from Peddle. The one vehicle they needed a phone call for was the highest-mileage car in the test. If your car is a common make and model, Wheelzy is likely to give you the best number of any instant buyer.
What Wheelzy says about selling a car with mechanical issues:
Find out what your car with a blown head gasket is worth in about 2 minutes.
Our take on CashForCars:CashForCars is owned by Copart, one of the biggest vehicle auction companies in the world with about 200 locations. They price cars based on what similar vehicles sell for at Copart auctions, which means their offers can be higher for cars that have strong parts or resale value even with a head gasket problem. They give instant online quotes in minutes and handle all the paperwork at pickup.
Pros
Auction-based pricing can produce strong offers for cars where the parts have value even with head gasket damage
Instant online quotes in minutes for most cars with blown head gaskets, no phone call needed
About 200 locations mean free towing is available quickly across most of the country
Cons
Gave the same flat $424 offer for 4 of our 5 test vehicles regardless of make or mileage, suggesting a set floor for common head gasket cars
Payment is by check only and your bank will hold it for about 24 hours before you can use the money
Won’t buy if you still owe money on the car
Why we picked it: CashForCars offered $755 for the 2000 Lexus SC 300 with 225,000 miles and a blown head gasket. That was the highest single offer in the entire test and more than double what Peddle offered for the same car. Copart’s auction network has strong demand for sportier and less common vehicles because they attract dedicated buyers who want specific parts. If your car isn’t a generic daily driver, CashForCars could surprise you.
What CashForCars says about buying cars with a blown head gasket:
CashForCars is backed by Copart and can price your car based on real auction demand, even with engine damage.
Our take on Peddle:Peddle buys cars with engine damage and doesn’t require you to prove the head gasket failure or get a diagnosis report. You describe the condition online, get an instant offer, and schedule free pickup within 24 to 48 hours. They buy cars that won’t start due to overheating or coolant leaks, which is common when a head gasket has failed completely.
Pros
Gives instant online quotes for cars with head gasket failures, including non-running vehicles
Free towing even if the engine overheating has left the car completely immovable
Quote stays valid for 7 days so you have time to compare offers from other buyers
Cons
Offers tend to be the lowest of the three instant buyers we tested on head gasket cars
Offer may change at pickup if the head gasket damage caused additional engine problems you didn’t describe
Won’t buy a car with a head gasket problem if you still owe money on it
Why we picked it: Peddle was the only service in our test that gave instant online quotes for every single vehicle, including the 2000 Lexus SC 300 with 225,000 miles where Wheelzy needed a phone call. Even though Peddle’s offers were lower on most cars, the ability to get a number in minutes without picking up the phone makes it the easiest starting point when comparing buyers. If you want to know your floor before calling anyone else, Peddle gives you that instantly.
What Peddle says about selling a car with a blown head gasket:
Get an instant online quote without a phone call, even on cars that won’t start.
Our take on CarBrain:CarBrain has been buying problem cars since 2007 and has bought close to a million vehicles. They give instant online quotes for most cars with blown head gaskets and provide free towing anywhere in the country. One thing that sets them apart: you can counter their first offer if you think the car is worth more. The engine and transmission need to still be in the car for them to make an offer.
Pros
You can counter their first offer, which can help when the rest of the car is in good shape despite the head gasket failure
Buys cars with blown head gaskets even if the engine can’t be started for a test
You get paid before the tow truck leaves with your car
Cons
Offers tend to run lower than Peddle or Wheelzy for the same head gasket car based on seller reports
Some sellers report getting lower offers than Peddle or Wheelzy for the same head gasket car
Title must be in your name before they can buy, so a recent purchase with head gasket damage may need paperwork first
Why we picked it: CarBrain is the only instant buyer in this list that openly lets you push back on their first offer. When your car has a blown head gasket but everything else works fine, the rest of the vehicle still has value. Being able to make a counter offer can recover some of that. Their 7-day quote window also gives you time to get offers from Peddle and Wheelzy before deciding who to sell to.
CarBrain lets you counter their first offer, which no other instant buyer on this list allows.
Our take on eBay Motors:eBay Motors is a listing platform where you set the price and sell directly to buyers. For a car with a blown head gasket, eBay reaches a national audience including buyers who specifically look for project cars, parts cars, and DIY repair opportunities. Some buyers will pay more than an instant buyer if they plan to fix the head gasket themselves or pull the car for parts.
The trade-off is you handle everything: photos, listing, buyer questions, and arranging pickup or shipping. There’s a flat listing fee of $19 to $79 depending on the package, plus you’re responsible for finding your own tow truck if the car won’t drive. It takes more time and effort than an instant sale, but can put more money in your pocket.
Best For Free Local Listings: Facebook Marketplace
Our take on Facebook Marketplace:Facebook Marketplace is free to list on and reaches local buyers directly. For a car with a blown head gasket, your best buyers are likely mechanics or DIY enthusiasts who know what the repair costs and have decided it’s worth it. Being upfront about the head gasket issue in your listing title saves you time by filtering out buyers who won’t follow through.
Listing is free but expect more messages than serious buyers. You handle all of the work including photographing the car, answering questions, meeting strangers, and arranging your own towing if the car won’t move. Selling privately this way can get you more money than an instant buyer, but it takes patience and more time.

What This Tells Us
What this tells us:
CashForCars, backed by Copart’s auction network, showed its biggest advantage on the least common car in the test. The more a vehicle has collector or parts appeal at auction, the more Copart’s network can do with it.
CashForCars gave the same offer for 4 different vehicles with very different mileage and make. This suggests their system applies a flat floor for common daily drivers with major engine damage rather than pricing each one differently.
Wheelzy required a phone call for the Lexus SC 300, the only vehicle in the test with over 200,000 miles and a less common body style. Their instant quote system appears to have limits on unusual or high-mileage vehicles.
Peddle gave consistent instant quotes on every vehicle across the board, including the one Wheelzy couldn’t price online. If you have a very high mileage or unusual vehicle, Peddle is the most reliable starting point for an instant number.
The gap between the highest and lowest offer was the widest on the Lexus SC 300. For common vehicles like the Camry, Hyundai Accent, and Subaru Outback, the difference between buyers was much smaller. The more specialized the vehicle, the more it pays to compare.
Wheelzy was willing to consider matching or beating a competitor quote if you ask. Getting a Peddle or CashForCars offer first gives you something to negotiate with when you call Wheelzy back.
If your car has a blown head gasket but most other components are intact, CarBrain’s counter offer option may be worth using. Buyers price head gasket cars conservatively because the damage signals unknown secondary problems, so there’s room to push back.
Getting quotes from Peddle, Wheelzy, and CashForCars takes about 10 minutes total and can show you a meaningful range. Your location and what each buyer needs in their network affects results, so the same car can get very different numbers in different markets.
Not sure which buyer will offer the most for your specific car? Use the comparison tool to get quotes from multiple buyers at once.
Yes. Peddle buys cars with blown head gaskets and doesn’t require you to have it repaired first. They accept cars that won’t start due to engine overheating or coolant system failure. Describe the condition honestly online and you’ll get an instant quote in minutes.
Does Wheelzy buy cars with a blown head gasket?
Yes. Wheelzy lists blown head gaskets as one of the mechanical issues they regularly buy cars with. They’ll tow the car for free whether it runs or not. For most common makes and models, you’ll get an instant quote online. Some less common or very high mileage vehicles may require a phone call instead.
Does CashForCars buy cars with a blown head gasket?
Yes. CashForCars is owned by Copart and specifically handles cars with mechanical problems including head gasket failures. They give instant online quotes and provide free towing. Their pricing is based on what similar vehicles sell for at Copart auctions, which means cars with parts value can get stronger offers.
Does CarBrain buy cars with a blown head gasket?
Yes. CarBrain buys cars with blown head gaskets as long as the engine and transmission are still in place. They give instant online quotes for most vehicles and let you counter their first offer. The title needs to be in your name before they can proceed.
How much is a car with a blown head gasket worth?
Based on our test, instant buyers offered between $350 and $755 for cars with blown head gaskets, depending on the make, model, and mileage. Common daily drivers with high mileage typically get offers in the $380 to $466 range. Less common or more desirable vehicles can get higher offers because buyers have more auction demand for their parts.
The same car can get very different offers from different buyers. Getting quotes from Peddle, Wheelzy, and CashForCars takes about 10 minutes and shows you a real range for your specific car.
Should I fix the head gasket before selling?
It depends on the car’s age and value. For older, high-mileage cars, the repair rarely makes financial sense. Head gasket repairs can cost $1,500 to $3,000 or more, and most older cars won’t sell for much more after the fix than they would as-is.
If your car is newer or lower mileage, the math might work out differently. Start by getting a repair estimate from a mechanic or using RepairPal to see what the fix would cost in your area. Then get instant quotes from a few buyers to see what the car is worth with the damage. If the repair adds more than it costs, fixing first is worth considering. If not, selling as-is is usually the smarter move.
Do I have to disclose the head gasket failure when selling?
Yes. All instant buyers ask about your car’s condition during the quote process. Describing the head gasket failure honestly means your quoted price is more likely to hold at pickup. If you leave out the damage and the driver finds it, the offer may change when they get there.
For private sales on eBay Motors or Facebook Marketplace, disclosing known mechanical issues is both a legal requirement in most states and a practical way to avoid the deal falling through after a test drive or inspection.
Can I sell a car with a blown head gasket if I don’t have the title?
Most instant buyers require a title in your name to complete the sale. Peddle can sometimes buy without a title in cases like deceased owner situations or lost titles, but it depends on your state. CarBrain and CashForCars require the title to be in your name before they can proceed.
How long does it take to sell a car with a blown head gasket?
With an instant buyer like Peddle, Wheelzy, or CashForCars, you can have the car picked up and get paid in 24 to 48 hours after accepting an offer. Getting the quote takes about 2 minutes online.
Selling on eBay Motors or Facebook Marketplace takes longer. Most private sales of problem cars take anywhere from a few days to several weeks depending on your asking price and how quickly you find a buyer who wants to take on the repair.
Will my offer change if the car won’t start at pickup?
Not if you described it accurately in the quote form. If you told the buyer the car won’t start due to head gasket failure and the driver confirms that’s the case, your price should hold. The risk of a price change comes from undisclosed damage that shows up at inspection, like a warped head or cracked block that you didn’t mention.
Methodology
We selected 5 vehicles with blown head gaskets across a range of makes, models, and mileage: a 2000 BMW 528 (125,651 miles), a 2000 Lexus SC 300 (225,000 miles), a 2003 Toyota Camry (228,776 miles), a 2008 Hyundai Accent (165,000 miles), and a 2008 Subaru Outback (172,745 miles). All were described as non-running or with active head gasket failure.
We submitted each vehicle to Peddle, Wheelzy, and CashForCars using the same Florida zip code and answered all condition questions honestly. We took screenshots of every result immediately after the quote was displayed.
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 request a quote.
