One support piece has a broken tab (please check last photo). The foam wheels that send the car are very dry and falling apart. I tested the motor drive that spins the foam wheels and it works great. I used modern Hot-Wheels cars to test with, and it didn’t send them very far (probably because of the decaying wheels and possibly they are bigger then the preferred cars for the set). Missing instructions and the two crack up cars. Box shows quite a few stress creases on the front. Feel free to ask any questions.
