EMPI started to produce fiberglas dune buggies in the late 60's. The bodies have curved fenders similar to a corvette of the same period. The hood has a single wide raised bump as well as the outline of the EMPI logo and words Imp as a bump on the front of the hood.

The bodies were produced in two styles - '68 & 69 with plain back seat areas and '70 with a place to mount a tach in the hood, a more vertical license plate mount on the hood and molded in back seats.
