What “Pre-purchase inspection” means
A PPI is done by a mechanic you choose, not one recommended by the seller. A good inspection covers the engine and transmission, brakes, tires, suspension, leaks, frame and body for accident repair, a computer scan for stored codes, and a road test. Many independent shops charge roughly $100 to $250, more for specialty or luxury cars.
For EVs, ask for a battery health check if the shop can do one.
How it shows up at the dealership
Most reputable dealers allow a PPI, sometimes at a nearby shop or with a mobile inspector. A seller who refuses an inspection is giving you useful information.
If you are buying from a private seller, a PPI is even more important, because there is no dealer warranty, no Buyers Guide and often no way to return the car.

What to say
“I’d like to have it inspected by my mechanic before I commit. If anything comes up, we can adjust the price or you can fix it before I sign.”
