What it is

You visit the car wherever it is, a seller's driveway or a dealer lot, and check body, tires, brakes, fluids, leaks, electronics and warning codes. You then send the buyer a clear written report with photos.

Your first three steps

  1. Build a repeatable inspection checklist and a sample report, and check what local competitors charge
  2. Buy a quality OBD-II scanner, paint thickness gauge, flashlight and basic tools, then price your first packages
  3. Set up a simple website and Google Business profile and post in local car-buying groups and forums to find your first clients
Who pays

Used car buyers, especially people buying from private sellers, out-of-town buyers, and families who want a second opinion before a big purchase.

How it makes money

A flat fee per inspection, with higher prices for trucks, luxury or specialty vehicles and for travel outside your core area. Some inspectors add rush or weekend rates.
