Hi Jay,
The kit consists of the polycarbonate body and rear wing, Beetle exhaust (which I didn't use cos I've got the tuned pipe!), Beetle undertray, stickers and a bag of screw/washers etc.
I bought mine from
http://www.rc-car-online.de/htstarteng.htm it's a rc shop based in Germany and cost me £105.
The Bug looks 1000% better than the buggie body supplied with the Marder and it makes the car look really really big!!
