I remember having one or two weird matchbox-type cars. They may be the same car, but I can't remember.
One aspect of it had a side that would look normal when flipped one way, but when something hit it, a spring inside flipped the doors around, and it looks like someone jacked it at an intersection.
The other aspect of it was a small spring-loaded arm on the bottom that would pop when the car hit a wall, and it would flip the car into the air. I'm afraid no amount of digging in my apartment or back home will yield results
