I'm old! haha! 42! I'm probably going to drive it on parking lots. I like the higher clearance of trucks that would make riding on grass possible, but on pavement, they're a little slower, right? I read most of the post you linked to so thanks. I'm not set on the scale or anything at the moment. I do like the idea of building it myself like the link recommended. Let me check out some of the cars on this thread.
