The Mosler J-10 Sport was a one-off automobile designed by Mosler Automotive and built mostly with existing General Motors parts.
The front half of the vehicle visually resembles that of the Jeep CJ and the rear half of the vehicle is taken from the Chevrolet S10 Pickup truck, although the frame and construction of the vehicle is mostly built from the latter of the two.
