The imaginative title of this topic is a pretty clear indication of what I intend putting here. Oddball stuff I come across in old magazines that I get around to scanning.
For starters, here's a couple of home brew American plastic cars, both featured in the June '64 issue of Hot Rod Magazine.
VW floorpan but with turbo Corvair engine in the back.
Except this one isn't plastic but hand formed in metal according to the text, and just cunningly disguised to look like plastic.
