i just bought 1. not from that place, from dandenong near the plaza.
cost me like 270 for the car and u assemble it FROM scratch EVERYthing like make ur own diff drive shaft even your own damper oil in your home made suspension and springs, then the remote was $100 (wtf?) i know, and battery was like 35, and charger was like 60, and red paint was 10 bucks.. so it all adds up but its loads of fun, does AWD burnouts and leaves marks on the kitchen floor lol.
I also dumped it on its ass looks hot (RX7)
