I did a Gloor Craft (Quality Craft) all-door box as my very first Craftsman car kit, gee, about 1974 or 1975 or so.
I distinctly remember how much work it was. Particularly filling all the wood parts to look like steel. Wood does a great job of wood, pretty poor on steel!
If you want a car without all that nasty cast-on plastic detail, nice wire door parts, and proper end details, this is the car for you. But I wouldn't make another one even if you paid me!
I still run the car today and it is one of my all-time favorites.
