Honestly, This could be a winner..
this coulda been GREAT! it just moved way to dang slow.. If i could offer a few pointers it would be to make it obviously faster, and throw in like a leveling tool for when your assembling the vehicle so the wheels can be flat on the ground and not have the wheels be oblong and uneven. But this is a fixer upper. you can easily make this into something fun and incredibly entertaining!
