I've got an HPI Nitro RS4 3 SS. Awesome little car, but I'm kicking myself because I haven't been able to drive it through the winter. Mine came w/ the Trans-Am WS6 body, but I'm planning to pick up one of the new Lotus Elise bodies they just released last week.
oh, and Fyi, 80mph, while possible, requires a lot of $$ over one of thier regular kits; my SS is one of if not the fastest 1/10 kit they have out of the box and it tops out around 45mph.
