Quick answer: A pre-purchase inspection (PPI) usually costs $100–$250 at an independent shop and $150–$300 from a mobile inspector who comes to the car. Luxury, exotic, EV and classic cars can cost $300–$500+. It’s almost always worth it: one hidden problem, such as a leaking head gasket or failing transmission, can cost thousands.

What a good inspection includes
- Diagnostic scan: stored and pending trouble codes, plus readiness monitors (which show if codes were recently cleared).
- Engine: leaks, noises, coolant and oil condition, belts and hoses, and sometimes a compression test.
- Transmission: fluid condition, shift quality on the road test.
- Brakes, tires and suspension: remaining life and uneven wear that points to alignment or suspension problems.
- Underbody: rust, frame damage, exhaust leaks and signs of past accident repairs.
- Electrical: battery, charging system, lights, windows and AC.
- Road test at different speeds.
- Hybrids and EVs: battery health tests where available; see Buying a Used Hybrid: Battery Checks.
Ask for a written report with photos and repair estimates for anything found.
Is a pre-purchase inspection worth it?
In most cases, yes. A $150 inspection can:
- reveal problems that make you walk away from a bad car,
- give you leverage to negotiate the price down by the cost of needed repairs,
- or confirm you’re buying a good car, which is worth the peace of mind.
It’s most valuable on private-party sales, cars sold “as-is”, and models with known expensive problems. See Cars With the Highest Repair Costs Over 10 Years.
How to arrange one
- Choose a shop or inspector you pick, not one recommended by the seller.
- Tell the seller upfront that the sale depends on an inspection. A seller who refuses is a red flag.
- For dealer cars, most dealers allow you to take the car to a nearby shop or let a mobile inspector come.
Frequently asked questions
Who pays for a pre-purchase inspection?
The buyer, in almost all cases.
How long does it take?
Usually 1–2 hours, plus time for a written report.
Does a dealer’s “certified” inspection replace a PPI?
Not entirely. Certified pre-owned programs add a warranty, which is valuable, but an independent inspection is still a good idea.
