Got to be careful, Last thing you want is the law catching you messing around driving (in or over) a stolen vehicle. Simple mindless fun could get you hard time.
Last one I drove on (local guys chipped in and bought a $100 dodge aries wagon at the auction for friday night powerline trail bashing fun)
When they were done on the power lines I put the front tires of the sammy on it and then on the roof. To slick to get the back tires up further. When I ligned back up to get both wheels up and over, I wedged the 35" boggers cleats in the windshield frame. Being open front with both back tires on the bumper / hood, I was stuck. Stuck on the powerlines with my front tire hung in the windshield of a car at about 1am and some how the other trucks had unknowingly left.
I had a little while to think about it before a friend noticed I was not out and returned to give me a tug.
