The one I had as a kid seemed to work fine. When I acquired one a number of years ago neither the car nor the corral worked well. After hours of tweaking the corral, ramps, and car platform it works OK, You will want to get a set of pads for the car and corral, then its a matter of small adjustments to optimize the vibrations. Because it was one of two operating accessories I grew up with as a kid I wanted it to work. It can be done, just takes a lot of trial and error.
