Used Car Pre-Purchase Inspection in Detroit

A pre-purchase inspection puts the car on a lift and tells you what the seller either does not know or is not saying, before your money changes hands. We check frame and rust, scan for stored and pending codes, test compression where warranted, look at fluid condition, and go over brakes, tyres and suspension. Private sales in Michigan are sold as-is, so the hour on the lift is your only protection, and finding a bad transmission beforehand saves you the entire purchase price.

  • You are buying privately and it is sold as-is
  • The listing says runs great with no other detail
  • The seller will not let you take it to a shop, which is its own answer
  • It is priced noticeably under similar cars
  • You are buying sight-unseen or from out of the area

What we actually do on this job

  • Full lift inspection of frame, subframe and rust condition

  • Road test and a written report you can negotiate with

Turnaround. About an hour with the car here. Book ahead so the lift is free.

What the price depends on

We do not publish a flat price for this, because a number quoted before anyone has looked at the car is a guess. You get a real one after the diagnosis, and you approve it before any work starts.

  • Whether a compression test is included for a higher-mileage engine
  • How long the road test needs to be to reproduce a reported fault
  • Vehicle type, since trucks and vans take longer on the lift

Pre-Purchase Inspection questions

What people ask us about pre-purchase inspection

What if the seller will not let me have the car inspected?

Walk away. A seller with nothing to hide has no reason to refuse an hour at a shop of your choosing, and a refusal is the clearest signal you will get. It is the single most reliable red flag in a private sale.

Will an inspection tell me if the car has frame damage?

In most cases yes. On the lift we can see repaired frame rails, welded sections, crumpled subframes, mismatched underbody coating and rust that a car wash and a photo listing hide completely. Combined with uneven panel gaps and paint depth, it usually gives a clear picture of whether the car has been hit.

Can you inspect a car that is at a dealership across town?

The car has to come to us so we can get it on the lift, but most sellers will allow a test drive to a nearby shop. Call us with the details and we will make time for it.
