My collection mostly consists of monster trucks, 70's era F1, Group C / Le Mans prototypes and the odd ones like semi trucks, 4x4's, GT cars and a Beetle (M-04 chassis). Some NIB and the others New Built.
I also have a collection of body sets and a lot of Juggernaut 2 axle parts.
Still need to take photos of everything and to update my showroom.
I'm also a big Sauber-Mercedes Group C Sports Prototype enthusiast with many books, posters and other collectibles.
