I hesitate to post something like this, but...
if anyone is wanting a nice buggy to convert, a buddy of mine is selling a Jammin X1CR roller cheap... less than 1/2 of new and it's a nice car with extra body, set of shocks, king heads parts...
This dude buys and seels stuff all the time. lol... he posted on a local forum... links to pics. I haven't even looked at them but here's the link:

The pipe is not included, btw... I just checked the pics :)
This is a killer deal imo... and a good guy to deal with... which is why I posted it.
