Wow, after half a gallon of fuel through my Smartech, I haven't got a mark on the body... Did you take some bad tumbles? Most cars will usually get damaged after a couple spills, especially if they hit something hard/stationary, like a curb, tree, etc.
I went through most screws when I got the car, and sure enough, there were some loose ones.

I am still waiting for a response to the question I had about the excelhobby differential pinion gears; If the 11257 gears are the same as the gears in 11258 gear and axle set... (they look different in the picture)
