RE: sportwerks mayhem pro vs turmoil
yes the mayhem and turmoil are two different cars. the turmoil used a fcg chassis and handled much better.
as far as finding parts you are going to have to get real comfortable with google and ebay. the sportweks line was discontinued a few years ago. there are still allot of parts out there but it takes allot of searching to get them.
there is a mayhem truggy. so if you can find the parts you can build it.
is it worth it? we're adults spending thousands on toy cars! its up to you
