Selling Damaged Cars

There is a large market in buying and selling damages cars.  There are entire auctions dedicated to selling damaged cars.

Insurance Auto Auctions sell thousands of damaged cars all over the country.

General Motors has an auction for GM dealers only for many types of cars.

Car Tech Auction sell mostly damages cars.

The point is that if you are buying a used car you must be very careful.  If you are buying a car you have to have the car inspected before you purchase the car. 
My BLOG has many posts on this issue.  There are thousands of these cars in the stream of commerce.  There is no single data base to check to see of the car was in an accident.  Car Fax is not the answer.  Car Fax does not have access to CLUE, Comprehensive Loss Underwriting Exchange, which is the largest database in the world for insurance claims paid.
