Each find is compared with recent sales of the same car in the same condition: a project against project sales, a show car against show cars. It has to come in at least 20% under, or be rare enough to be worth knowing about. Then we read the listing for red flags. We don't inspect the cars, so see one in person or pay for an inspection, never wire money to hold a car, and make sure the VIN on the title matches the car.
