I've been looking at base vehicles for a few years now. I wanted a duel use set of wheels so I can play with it off road when not at burning man. Ideal base would have been an Argo 8 wheeler, but way too expensive. Golf carts have some inhernt problems IMO. Electric just doesn't quite make it on the Playa. As much as I've tried with the two small electric MV I made so far, the amount of power needed for recharging and the charge times just make them a pain. Gas powered golfcarts just seem underpowered as well. I wanted enough power to tow other MV cars if needed (had this done for me one year and was grateful) or maybe be able to tow bikers or boarders. I also wanted a low profile to mount the shell on. The KIng Cobra cart I'm using is one of the only made that meets California clean air green sticker standards, and its relativly cheep compared to things like a Polaris or ATV. The shape of the roll cage also follows the general shape of the Chaffee, which will make bolting the shell to the frame eaiser. At the same time the engine is only 150 cc so it wont be too obnoxious on pollution or gas.
Buggy modifications for the Playa will be enhanced muffler system to make it quiet, performance air filter system for the dust,and a racing fan to make sure there is enough airflow in the shell. Lighting system is going to replicate "warp core" effect in the front and back of the engine pods, and several sets of computer controlled LED ropes. Amazing the stuff you can get cheep on ebay
