Is that the car featured in Grassroots Motorsports? If so, it's all encompassingly rad! If not - still rad, can't beat tiny cars with big motors. The kit with the engine is the Tamiya LS400/Celsior. I think it was issued here as the LS400, but is more easily found on on Ebay as the Celsior. I got mine for $11+shipping, which isn't bad for a motor, and a GIANT spare body for paintwork practice. It will make a cool slammer.
And Oli, what's wrong with my wheels? I like them
