RE: tamiya confusion
I believe the Jeep comes with a light kit (and possibly something else) which adds to the cost.
I believe J.D.T. is correct, the XC is a slightly shorter wheelbase version of the CC01. I think the chassis itself may actually be the same, but the rear suspension uses a further back mounting point on the CC01. Someone can correct me if I'm wrong, but I believe that's the case.
