These models are nice. I don't think you're using blender or milkshape for these.
Once you get it, make it look like one of your speedkarts.:P
I dare you to get the yellow one.
Is there a specific website you're getting them from or anything so I can check out possible prices?
looks sort of like the Mario Kart 64 kart
Make sure you either have places to ride it or are good at hiding from the cops. Like my ATV, riding karts on the street is highly illegal.
i'll be saving up for one of thesemight take a while though
