Pre-purchase car inspection: what to know

What the job involves, what changes the price, and what to ask a pro.

What pre-purchase car inspection is

An inspector checks a used car's engine, frame, brakes, tires, fluids and electronics, then gives you a written report so you can decide before you buy. You need it before paying for a used car, especially from a private seller or a car you have not driven before.

Signs you need it

  • You are buying a used car from a private seller or a small lot
  • The seller will not let you take the car to your own mechanic
  • The car has a title problem, a rebuilt history or a recent accident report
  • The car has warning lights, fresh paint or a strong smell that might hide a problem
  • The car has been sitting for a long time or has high mileage for its age

What the pro does

  • Reviews the vehicle history and asks about past repairs and accidents
  • Checks the engine, fluids, belts and hoses for leaks, wear and damage
  • Inspects the frame, suspension, brakes and tires for damage and wear
  • Tests the electronics, lights, air conditioning and warning systems
  • Writes a detailed report with photos and recommended repairs

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • The make, model and year, and how complex its systems are
  • Whether the inspector must drive the car to a separate test site
  • Whether the car is inspected at the seller's location or at a shop
  • Whether a road test is included or only a static check
  • Whether a scan of the computer systems is included
  • Whether a longer or more detailed inspection is requested

What a written quote should spell out

  • The areas inspected, such as engine, frame, brakes, tires and electronics
  • Whether a road test and computer scan are included
  • A written report with photos and a list of findings
  • Whether the inspector will come to the car or you must bring it
  • Whether a follow up call or a second look is included

Questions to ask before you hire

  • Will you give me a written report with photos of each finding?
  • Do you check for frame damage or signs of a previous accident?
  • Will you scan the computer for stored codes?
  • Can you tell me which repairs are urgent and which can wait?
  • Do you test drive the car, and in what conditions?
  • Do you have any conflict of interest with the seller or the dealer?

Red flags

  • Works for the seller or a dealer and will not say so
  • Gives a verbal report only, with no written findings
  • Will not inspect cold or will not road test the car
  • Recommends a repair without showing the reason

What you can do yourself

You can check the vehicle history report, look for uneven tire wear, test the lights and windows, and check for leaks on the ground after the car has been parked. Do not rely on your own check for the frame, brakes, suspension or electronics. Hire an independent inspector before you commit to buying the car.

Licenses and permits

A license is usually not required for a pre-purchase inspection. Check with your state or local licensing agency about any business registration that applies, and ask the inspector to show its insurance and training.

Pre-purchase car inspection questions

Is an inspection worth it on a cheap car?

It can be, because a hidden problem can cost more than the car is worth. Ask the inspector what they can find on the car you are considering.

What if the seller will not allow an inspection?

Take that as a serious warning sign. Most honest sellers allow an inspection by an independent inspector.

Should I buy a car with problems listed in the report?

That depends on the problems and the price you pay. Use the report to ask for a lower price or to walk away.
