The short answer
A professional pre-purchase inspection for a standard passenger car usually costs between $100 and $250 in the U.S. Specialty, luxury, or classic cars can run $300 to $600+ because they require a mechanic with specific expertise and often more time.
What drives the price
- Location — Urban and coastal markets (NYC, LA, San Francisco) typically charge more than rural or Midwest shops.
- Who performs it — A mobile inspection service like Lemon Squad or AIM Certify often charges a flat rate. A dealership or specialized shop may bill hourly.
- Depth of the inspection — A basic 50-point checklist is cheaper than a full diagnostic scan, compression test, and undercarriage photos.
- Vehicle type — European luxury, diesel trucks, and EVs usually need brand-specific tools or training, which raises the price.
- Travel distance — Mobile inspectors sometimes add a mileage surcharge if the car is outside their standard radius.
Typical price ranges by provider
- Independent mobile inspector — $150–$250 for most cars.
- Nationwide mobile service — $170–$300 depending on add-ons.
- Local mechanic shop — $100–$200 if they offer a pre-set PPI package.
- Dealership service department — $200–$400; usually the most thorough, but also the most expensive.
- Specialty / exotic / classic — $350–$800+ for marque-specific expertise.
Is it worth paying for?
Yes — if the car is expensive or you are not comfortable spotting problems yourself. A $200 inspection that reveals a $1,500 hidden transmission issue pays for itself instantly. It also gives you leverage in negotiation.
On a $4,000 commuter from a private seller, though, a $200 PPI is 5% of the purchase price. That is where athorough DIY checklist can do most of the same work for free.
What you should expect for your money
At minimum, a paid inspection should include a written report with photos, a severity rating for each finding, and an estimated repair cost. If the inspector only gives you a verbal thumbs-up, you did not get your money's worth.
How long does it take?
A basic pre-purchase inspection takes 1 to 2 hours on-site. A deeper diagnostic with a test drive and scan-tool session can stretch to 3 hours. Mobile inspectors usually book 24–48 hours out, so do not wait until you are at the dealership to schedule one.
