Listed today at The Motor Shed, Bicester. Last checked today.
The Speed 20 was Alvis's sporting offering of the mid-1930s, a pre-war six-cylinder car with a reputation for taut steering and strong brakes. This 1936 example wears Charlesworth saloon coachwork on the SD chassis and is powered by the 2,762cc overhead-valve six.
It is an older restoration that the dealer describes as sound and mellowed. The engine is reported to be in good condition with no signs of overheating, and the car is said to drive well. The bodywork is sound, though the paint is generally poor, while the interior is tidy.
Bills and history are said to go back to the mid-1950s, which gives a useful paper trail for a car of this age.
