Start with what the SS Jaguar 100 is: a open Roadster (automobile) / two-seater / 2-seater Hardtop / fixed head coupé (one-off) with 2663 , built from 1936 to 1939, when streamlining and independent suspension were arriving together. What it meant takes a little longer. 314 were built.
The background
The SS Jaguar 100 is a British 2-seat sports car built between 1936 and 1939 by SS Cars Ltd of Coventry, England. The manufacturer's name 'SS Cars' used from 1934 maintained a link to the previous owner, Swallow Sidecar, founded in 1922 by Walmsley and Lyons to build motorcycle sidecars. In March 1945 the S.
S. Cars shareholders agreed to change the name to Jaguar Cars Limited. In common with many products of the thirties, the adoption of an animal name was deemed appropriate and the model name "Jaguar" was given to a new SS saloon car in 1935, and then to all new SS models. The '100' was for the theoretical 100 mph maximum speed of the vehicle.

The engine is 2663 other versions carried different engines, listed in the specification table below. On the scales it comes to 1043 kg. Drive goes through a 4-speed manual. The wheelbase is 104 in. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
In the Jaguar Cars line-up the SS Jaguar 100 has a clear place: it replaced the SS 90; it handed the line to the Jaguar XK120; the factory was Coventry, United Kingdom. The cars a buyer would have weighed it against include the Bugatti Type 57, the Volkswagen Beetle, the Chevrolet Suburban. Its Jaguar Cars stablemates include the Daimler Sovereign and the Prime Ministerial Car.
Owning one today
There is no federal ownership record for the SS Jaguar 100 — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
