EMPI a Volkswagen aftermarket company started to produce fiberglass dune buggies in the late 1960s. 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 tachometer in the hood, a more vertical license plate mount on the hood and molded-in rear seats.
