The Jaguar SS100 was designed by William Lyons and Harry Weslake and was one of the first cars to feature an independent front suspension. The car was powered by a 2.5-liter inline-six engine that produced 104 horsepower.

The SS100 made its debut at the 1936 London Motor Show and was an immediate success. The car's sleek design and impressive performance made it popular with racing enthusiasts, and it soon became a favorite among celebrities and wealthy individuals.

During its production run, the SS100 underwent several changes and upgrades. In 1938, the car was fitted with a larger 3.5-liter engine that produced 125 horsepower. The car also received a new four-speed gearbox and improved brakes.

Despite its popularity, production of the SS100 came to an end in 1939 due to the outbreak of World War II. The factory was converted to produce aircraft components, and Jaguar Cars Ltd had to wait until 1948 to launch their next sports car, the XK120.

Today, the Jaguar SS100 is considered a classic car and is highly sought after by collectors and enthusiasts. The car's elegant design, powerful engine, and racing pedigree have made it one of the most iconic sports cars of the pre-war era.

Owned by the current lady owner/driver for the past three decades or so; this is the 4th from last car produced out of 118 total examples ever made. This is a well-known car in Swiss Rally circles and is now being sold due to the onset of old age and a bad back from the lady's husband who can no longer get in the car. It shares garage space with a Gullwing Mercedes and a 300 Roadster. The car comes with a massive history file showing a full restoration to concours condition at the time of purchase. Since then, the car has been regularly used with money spent upon it as required to keep it in tip top condition. The owner even went as far as re-tempering the springs back to factory spec to ensure the correct ride height and handling characteristics. Massive maintenance invoices come with the car attesting to the level of care the car has received. It starts instantly and drives exactly as one of these should. Exterior paint is mid metallic blue in fine order. To the interior are lightly patinated grey leather seats along with grey carpets. The hood is in reportedly good order although we did not put it up when photographing the car as the lady informed us it had not been used during her tenure. The car is showing 87,000 miles from new and is a matching numbers example with original engine number 1076 in situ. All instruments and details are likewise correct as when new.
The car has a current FIVA Passport in category A3 in the name of the current lady owner. There are also pictures of the car in bare aluminium at the time of its restoration.
These are rare cars that seldom come to market in 3.5-liter form and even more rarely form such long term careful ownership. It is a very collectable car of museum quality which benefits from having been regularly and carefully used. It is a thing of great beauty.
