I'm not sure how much it counts as "vintage," but I've been playing with the Traxxas 2wd platform and designing/making my own parts for it. I always kind of looked down on Traxxas stuff, but their race buggies from the 80's/90's look really impressive and the current cars are pretty much the same car just made from cheaper injection molded parts. In my eyes that counts as vintage

Anyway, when I get some time I'll post my traxxas builds. I think you guys will enjoy what I've done and the vintage inspiration I've drawn from while doing them.
