A well-prepared car sells faster and for more money. That doesn't mean fixing everything. It means knowing exactly what condition your car is in, fixing the things that pay you back, and being upfront about the rest.
A pre-sale inspection is how you find out. Here's what it covers, what it costs, and how to decide what to fix.
Key numbers
- Inspection cost
- About $286 for a mobile exotic-car inspection from Lemon Squad. Specialist shops set their own prices.
- Worth fixing
- Cheap, visible and safety items: warning lights, bulbs, windshield chips, worn brakes and old tires.
- Usually not worth it
- Big repairs right before a sale, especially if you're selling to a dealer.
- Always do
- Have open recalls fixed, which is free, and gather every service record.
Why inspect before you sell
Anyone paying serious money for your car will have it inspected. Specialist buyers check the car before they pay, private buyers ask for a pre-purchase inspection, and auction bidders ask for one in the comments. The only question is whether you learn what's wrong before they do.
- No surprises. A fault found by the buyer at the last minute becomes a reason to cut the offer, or to walk away. Found by you, it's something you can fix, price in or explain.
- It reassures buyers. Kelley Blue Book calls pre-sale inspections worth the investment for that reason, and notes that a buyer who sees one may not feel the need to order their own.
- You price it right. You'll know whether your car belongs at the top or the middle of the range for its model.
- The report sells the car. A clean report from a known shop, shared with buyers, answers most of their questions before they ask.
What a pre-sale inspection covers
A good inspection is the same one a careful buyer would order. Expect it to cover:
- A scan of the car's computers for stored fault codes
- Leaks, belts, hoses and fluid condition
- Brake pad and rotor life
- Tire tread and tire age
- Suspension and steering
- Paint and body, including signs of past repairs
- Glass, lights, the interior and the electronics
- A road test
Exotic cars add a few checks of their own. Ask for the ones that apply to your car:
- Porsche: a DME over-rev report on manual and GT cars, and a borescope inspection on the engines known for bore scoring. See what a Porsche PPI covers and costs.
- Older Ferraris and Lamborghinis with automated single-clutch gearboxes: a clutch wear reading from the diagnostic tool. Buyers ask for it.
- Any car: a paint-thickness reading on every panel, which shows whether the paint is original.
A mobile inspector is quick and convenient. A brand specialist with a lift and the factory diagnostic tool goes deeper, and its name on the report carries more weight with buyers.
What a pre-sale inspection costs
| Inspection | Price |
|---|---|
| Lemon Squad standard inspection | $220 |
| Lemon Squad exotic inspection, for cars such as Porsche and Lamborghini | $285.99 |
| Independent brand specialist | Varies. Ask for the price and exactly what's included. |
Lemon Squad prices are from its own site, checked October 2026. It is a nationwide mobile inspection company, and its exotic inspection includes a fault-code scan, steering and brake checks, a road test and more than 25 photos.
Set against a six-figure sale, either price is small. To find a specialist, see our list of independent exotic car repair shops by state.
What's worth fixing
The fixes that pay are cheap, visible, or about safety. They're the things a buyer notices in the first five minutes, and the things an appraiser marks down on sight.
| Fix | Why it pays |
|---|---|
| Warning lights | Nothing scares a buyer faster. Have the cause diagnosed, even if you decide not to repair it. |
| Open recalls | Free. NHTSA says to contact a dealer to have a recalled part fixed for free, and its website checks any car by VIN. |
| Bulbs and windshield chips | Kelley Blue Book recommends replacing burned-out lights and fixing chips and cracks before you sell. |
| Worn brakes | A safety item, and one of the first things an inspection reports. |
| Old or worn tires | NHTSA notes that some vehicle and tire makers recommend replacing tires that are six to 10 years old, whatever the tread. |
| Overdue service | A service that's due is the first thing a buyer subtracts. Done and documented, it's a selling point. |
| A proper detail | Kelley Blue Book says a thorough cleaning can raise a car's value, and that basic detailing can cost a few hundred dollars. |

Tire age catches out many exotic car owners. A car that covers 1,000 miles a year can have deep tread on tires that are far too old. The last four digits of the DOT number on the sidewall give the week and year the tire was made.
How much do these fixes add? For ordinary cars, Kelley Blue Book says minor repairs and a clean car can add hundreds to a trade-in offer. On an exotic car the bigger gain is usually in what you avoid: a buyer who starts doubting the car.

What usually isn't worth fixing
- Big mechanical repairs, if you're selling to a dealer or specialist. Kelley Blue Book notes that a dealer's offer already allows for estimated repair costs. A professional buyer can usually have the work done for less than you can, so a repair you pay for at retail rarely comes back in full.
- Repainting. On an exotic car, original paint is worth more than fresh paint. Buyers measure paint thickness, and a resprayed panel raises questions about accident damage. Have a detailer correct and polish the paint you have.
- Parts with life left in them. Don't replace a clutch or a set of brakes that still has plenty of wear left. Have the remaining life measured and put it in writing.
- Buying parts to undo modifications. If you still have the original parts, refit them or include them with the car. Don't buy new ones.
- Upgrades. New wheels, a new stereo or a fresh wrap won't return what they cost.
The exception is a fault that stops the car selling at all. If it won't drive, won't pass a state inspection, or shows a warning light with a cheap cause, fixing it opens the car up to far more buyers.
Selling a car that needs repairs
You can sell a car with a known problem. What you can't do is hide it. It will be found at the buyer's inspection, and a deal that collapses there costs you time and credibility.
- Get a written diagnosis and estimate. A named fault with a price next to it is far less frightening to a buyer than a mystery noise.
- Ask for offers on the car as it is. Dealers and specialist buyers buy cars that need work all the time, because they have shops of their own. Tell them about the problem up front.
- Compare the two routes. Set the cost of the repair against the difference between the as-is offers and what the car would bring once fixed.
- Describe it honestly. Kelley Blue Book's advice to sellers is to be honest about the car's condition. In an auction listing, put the fault and the estimate in the description.
A simple rule: fix it if the repair clearly costs less than the price it adds. If you can't tell, get the offer both ways.
Ask the buyer before you spend
If you're selling to a dealer or a specialist buyer, the cheapest way to settle the question is to ask them. Send the inspection report and ask two things: what will you pay for the car as it sits, and what would you pay if I had this fixed first?
Often the answer is that they'd rather do the work themselves. That tells you exactly what the repair is worth, before you've spent anything.
How selling works explains how to compare offers from different kinds of buyer.
Paperwork that adds value
- Every service record. Kelley Blue Book says a maintenance history boosts both price and buyer confidence, and that your dealer or mechanic can give you a summary if you've lost receipts.
- The inspection report itself.
- Both keys, the manuals and the original window sticker.
- Original parts, if the car has been modified.
- Receipts for recent tires, brakes or major services.
Block out personal details such as your address before you share records with a private buyer.
Common questions
Should I get my car inspected before selling it?
For any valuable car, yes. A serious buyer will inspect it anyway, so it's better to learn what's wrong first. Kelley Blue Book calls pre-sale inspections worth the investment because they reassure buyers.
How much does a pre-sale car inspection cost?
Lemon Squad, a nationwide mobile inspection company, charges $220 for a standard inspection and $285.99 for an exotic one, according to its site in October 2026. Brand specialists set their own prices.
Should I fix my car before selling it?
Fix the cheap, visible and safety items: warning lights, bulbs, windshield chips, worn brakes and old tires. Big repairs right before a sale usually don't pay you back, especially if you're selling to a dealer.
Should I replace the tires before selling a car?
Only if they're worn or old. NHTSA notes that some vehicle and tire makers recommend replacing tires that are six to 10 years old, whatever the tread. Otherwise leave them.
Can I sell a car that needs repairs?
Yes. Get a written diagnosis and estimate, and tell buyers about the problem. Dealers and specialist buyers buy cars as they are and adjust the price.
Is it worth detailing a car before selling it?
Usually. Kelley Blue Book says a thorough cleaning can raise a car's value, and that basic detailing can cost a few hundred dollars.
