1988 Ford Escort - 1.9l motor - Paid $65.
I bought this car and ran it in a derby in my friends backyard. We basically just drove around and beat on the cars a bunch. The Escort lasted quite awhile considering the cv joint was bad. I lost spark on the car and just left it for dead, since it was a "disposable car" anyway.
