That www.mini-koleso.ru is a gold mine of strange and unusual diecasts! I just found that deAgostini sold a collection of USSR cars there. There are so many nice models, and many of them you can find on eBay at reasonable prices!
Nami Belka - what a cute little car!
Microbus Start - complete with fishtails!
GAZ 13C Chalka - Save the wagons
CMZ C-1L - Looks like a Dalek from behind
