1991 Porsche 911 Carrera 4 Leichtbau Navigation
This particular example is the 15th serialized example and has the optional 7- and 9-inch wheels. Its first owner was Mike Amalfitano, who negotiated with the EPA and DOT to successfully petition then-New Hampshire governor Judd Gregg to help him legally import it to the U.S. for competition-only use. Although it was intended to race the Mt. Washington Auto Road Hillclimb, it never competed. In fact, it has reportedly never competed.

It currently has just under 4,500 kilometers on the odometer.
