Along with the Monogram track (posted elsewhere), I was fortunate to score 2 vintage Cox cars.
The mag chassis Chaparral 2D has a broken and repaired guide tongue:
The tupperware iso-fulcrum Chaparral 2E:
Both cars are runners, which is fine....I didn't have either one before and the price was right....free for the asking.
They came with what I believe are two Monogram F1 chassis....
All in all, a decent find and good restoration projects for this winter.
