I never jumped my car but I did let some chick drive my car once and she curbed it doing 55km and the car did get airborn (the curb was about half a foot high :cry) lets just say that my wheel bearings were shot, 1 bent rim and 2 blown tires and nice dent in my wallet

. My lesson learned A BLONDES WILL NEVER DRIVE MY CAR AGAIN.
