Yes. I remember.
My favorite thing to buy was the "3-n-1" model car kit.
The mfg gave you enough parts to build one car. But you could build it in 3 different ways:
- As if it came straight off the factory floor as a "family car" with no options.
- As if it was customized as a hot rod, "jalopy" or street racer.
- As if it was customized for a professional stock car race.
But if you bought several kits and saved all of the spare (extra) parts . . . eventually you would have enough parts to be able to build a completely original, one-of-a-kind, custom car! For FREE!!!
I would even use the injection mold "runners" that the parts were attached to, to build custom frames, suspension and steering systems and roll-cages.
(I am referring to the extra pieces of "throw-away" plastic that came in the kits from the injection mold machine at the factory that you snapped the parts off of.)
