Get a Carfax! I wanna know:

I can live with scratch and dent, total rebuild, not so much.

List of original equipment.

Original mileage.

Clean one owner, great.

Owned by a small group of friends who only raced on weekends, maybe.

Just came out of the rental fleet where it got drove hard, no thanks.

A Rule with No Exceptions: Remember if it has tits or tires eventually you are going to have trouble with it!
