How to Choose a Pre-Purchase Inspection Company
A good inspection costs a few hundred dollars and can save you thousands. Here is how to tell a good one from a quick look and a checklist.
What a Real Inspection Covers
The inspector should look at the engine, transmission, brakes, suspension, tires, body, paint, electrical system, cooling system, air conditioning and interior. They should plug a scan tool into the car and read every module, not just the engine light. Then they should drive it.
Ask for the number of checkpoints. Under 100 usually means a fast walk around. Over 120 means they open the hood and get under the car.
What It Should Cost
National companies charge from about $180 for a standard car. Expect more for a diesel truck, an exotic, an EV battery check or an RV. Tests that mean taking parts off, like a compression test, cost extra at every company, and a good one asks you first.
Red Flags
- No sample report on the website
- The seller picks the inspector
- No road test
- No scan tool, or only a code reader for the engine light
- No photos in the report
- Three or more days to get the report while the seller has other buyers
Questions to Ask Before You Book
- Who does the inspection, and are they an ASE certified tech?
- Do you go to the car, or does the car come to you?
- Will you drive the car?
- When will I get the report?
- Can I call the inspector after I read it?
- What costs extra, and will you ask me first?
