1970 Porsche 917 K

The Porsche 917 K was the direct result of years of intense research. Although it employed the most modern concepts in automotive design, the new car was absolutely in keeping with Porsche tradition.

1959 W.R.E.-Maserati

The 1950s saw a surge in the popularity of small-displacement 4-cylinder engines. Few were as influential as the engine that powered Maserati’s 200S sports racer. The competition-proven Modena powerplant attracted significant interest from privateers running other makes, and the company was only too happy to sell engines to such concerns, […]

1965 Alfa Romeo Giulia Sprint GTA

While most GTAs were either supplied in Stradale form or subsequently upgraded to Corsa specification, chassis AR752675 was destined for competition from the outset.

Available with powerplants from Nissan, Honda HPD, Lotus and, as with this example, the Judd BMW M3 V8, the Lola B1280 was the LMP2 version of the larger B08/60 chassis. With the large spinal fin, the car featured excellent stability at speed — a must for a car designed to […]

Lightweight, affordable and easy to construct, Devin’s fiberglass sports car quickly earned him a stellar reputation, and Devins could be found competing on racetracks across America. […]

1959 Bocar XP-5

The outrageous Bocar of the 1950s was the dream of Bob Carnes, who constructed the cars in Denver, CO. No two were alike. Six iterations were built through 1961, when a fire engulfed the Bocar shop and production ceased. Some 40 complete cars are believed to have been built, including […]

1934 Alfa Romeo Tipo B P3

Chassis 50006 is the sixth example of the seven Alfa Romeo Tipo B P3 second-series wide-body cars, and it is one of three originally fitted with the Dubonnet suspension and reversed quarter-elliptical leaf springs (as opposed to being converted by the factory following initial manufacture). Stamped with Scuderia Ferrari number […]

1963 Jaguar E-Type Lightweight Competition

  Chassis S850667 is the 10th example of the 12 E-type Lightweights built.
