A buddy of mine has one and it is VERY fast! Not as sure about the dependability. The only real problem he has is that the cap on the front shocks keeps popping off, and one of the universal joints has a crack in it. This thing is so fast that it's hard to drive on dirt, just breaks traction. Will throw tires off the rim too. The 2.5 is wild in this truck. It was a little fussy at first, but now it's great. I would like to see it in 4wd.
