Another thing I learned with these kits is that they work much better if you solder the chassis pans together rather than depending on the nuts and screws.
Once set up, use silver solder and Stay-brite flux to weld the parts solid with a good clean up later will result in a chassis that is solid and will NOT come apart.
Used to be back in the mid 60's that all model car kits could also be used to build slot cars. Until vacuum formed bodies became mainstream, all slot cars WERE made with injection molded scale bodies.
A manufacturer who made a new slot car kit of a Ferrari 275 P for instance, also figured out a way to sell it as a static model kit and thus amortise the cost of the molds over a wide range of the hobby.
It was the speed freaks who necessatated the need for vacuum formed bodies... and later the squashed "handling bodies" that really ruined the hobby.
But... all good things eventually come back around.

Staying in the theme of car movies:
"Lotta people go through life doing things badly. Racing's important to men who do it well. When you're racing, it's life. Anything that happens before or after is just waiting."
