After crashing his XK120 chassis 670191 in the Pebble Beach Road Races, Don Parkingson kept the remains and transformed them into this unique special.
A new body lightweight aluminum body was fitted design by Robert Cumberford and executed by Marvin Faw.
Joe Thrall did most of the mechanical upgrades including repositioning the engine nearly 10 inches back in the chassis. As a result the driver nearly sat over the rear wheels.
With upgraded brakes and an upgraded valvetrain, the Jaguar-Parkingson Special was ready near the end of the 1951 season. Don won the Palm Spring Road Race outright and he would remain in SCCA racing for 1952 and 1953.
This car was fully restored in 1983 with help from Marvin Faw who manufactured the original body. It continues to be vintage raced in California.
