Just picked up several Cararama's on eBay UK last week. Here's what I have:

1:43 - Foxfire, Red, Blue, Proton (yellow), Silver
1:72 - Foxfire, Blue, Purple (Peacock?), Silver

I believe Cararama made them in only six colors, so right now I lack a 1:43 Purple/Peacock, a 1:72 Red, and a 1:72 Proton/Yellow. Should be picking up the 1:43 Red this week though.

Having looked over all the models in Cyrk's collection as well as the Japanese guy's website, I really do think the Cararama/Hongwell models are the best quality. Too bad they didn't make anything in a 1:18 scale.
