Aoshima produce tons of plastic model kits in all shapes and sizes, but also make some very nice 1:64 diecast models. I've had the Gran Champion series since I started, but they're getting harder and harder to find. I'm also now starting to pick up some other bits and bobs.

The Grand Champion series includes six car models with two colour variants, and chases. One individual box includes one car model. These are popular!
