5 or more cars well shiz I have 1 and I've been working on it daily, trying to make it better, testing it, enjoying it, fixing problems, etc. Right now I have to fix one of those stupid brittle steering wires, you know, the ones that are right in your #$%^ing way when you try to change the battery? The unnecessarily thin things that can be broken and are a huge pain in the ass to fix? Yeah, thats my current project.
