Here we offer this highly significant and important example of the MG K3 breed, the 1,100-cc supercharged cars from Abingdon-on-Thames, which did so much to enhance the prestige of the British motor industry.

1955 Ferrari 410 Sport Spider

Despite Enzo Ferrari’s determination to win the 1955 World Sportscar Championship, very little went to plan that season. The new 118 and 121 LM 6-cylinder models did not pan out as projected, forcing Ferrari to revert to his 4-cylinder cars. And the disaster at Le Mans drew increasing scrutiny from […]

1977 Tyrrell P34

The six-wheeled Tyrrell P34 was a pet project of designer Derek Gardner, who had come up with the idea while he was working on four-wheel-drive systems for Indianapolis cars during the late 1960s. A few years later, and with the majority of the Formula 1 grid using the same Ford-Cosworth […]

1975 Chevron B31

Derek Bennett, a shy, intuitive engineer and vastly underrated driver, was once dubbed Britain’s Enzo Ferrari. Yet his most stunning, world-beating Chevron cars emerged from the gloom of a lofty old brick-built Lancashire cotton mill in Bolton’s Old Chorley Road.

1980 BMW M1 “Procar”

The BMW M1 was launched in 1978 but could not compete in the World Sports Car Championship due to a change in regulations. Therefore, Jochen Neerpasch (director of the BMW Motorsport Department) developed the Procar Championship as a venue for the model to race. There were two editions in 1979 […]

This fascinating 1969 Shelby GT350 race car, serial number 480033, began life as a Silver Jade GT500 sold new in Hayward, CA, on August 28, 1969. Shortly after its initial purchase, the car was stolen and damaged. The insurance company, unwilling to repair what it considered an “exotic” car, cashed […]
