    1948 Healey Elliott Sports Saloon

    The Donald Healey Motor Company completed its first car in 1945, going into full-time production in a disused RAF hangar in Warwick the following year.

    1923 Mercedes Type 122 Indianapolis Racer

    Following the Great War, Daimler began to consider forced induction using a supercharger.

  • 1936 Delahaye 135 S

    1936 Delahaye 135 S

    Of all the pre-war French racers, few are as well regarded as the Delahaye 135 S. Just 20 of these lightened and shortened speed machines were ever built, each doing battle at the very pinnacle of Grand Prix and sports-car racing.
