Ma shizzle (sorry, I've always wanted to say this):
My collection mostly consists of lots of Evos, some Rally cars and American muscle/classics, and bikes. Ironically, I'm scared to death to ride a motorcycle, but I love them, nonetheless. I like "interesting cars," like Citroens, Fiat 500s, vintage Volkswagens, and of course Evos. I also have a soft spot for the original Audi Quattros, and modern AWD rally cars.
I like 1:18, 1:24, and 1:32/36 models, but I do have several 1:43 Evos including a VI police car
Unfortunately, I'm running out of room, so I ordered another case for my office, along with more cars.
