RE: how much is this worth
get an XTM X-Cellerator. i myself have one and they are very good trucks. they are very fast, SCARY fast! one magazine confirmed its top speed at 50 miles an hour, and rc car action claimed 46mph. and it is cheaper than the rustler and the rc10GT. you shoulld check it out. heres their website: xtm.globalhobby.com
oh yeah and it also has very nice threaded shock bodies!
