I think a 1/8 buggy would be right up your alley. Big enough to be good off-road, nimble enough to be fun on-road with slicks, and hell-for-stout. Plus, if you ever make it out to Jefferson, you could race it at Dirtrunners' track during the outdoor season. A large scale car would be nice too, but depending where you are, finding a lot big enough to run it might be an issue......I'm guessing you're somewhere in the Bergen/Essex/Hudson area?
