If you thought the Stebbins was unique, how about the 1964 René Bonnet D’jet II? Its designer, Bonnet, intended it as a road car, building 181, but most were used as race cars. The D/jet made almost 100 horsepower from its mid-mounted 1149-cc Renault engine. We can imagine that, with its tubular frame, fiberglass body, and four-wheel disc brakes, it must have been quite an impressive performer back in its day.
