The Jensen Interceptor is a British-built, high performance car, with a 6.5 liter Chrysler engine and Torqueflite automatic transmission, which combines the best British coachbuilding and quality engineering with American power and smoothness.
These superlative cars are being built but the craftsmen at the Jensen factory at West Breenwich, and the top speed approaching 140mph and dynamic acceleration, combined with the turbine like smoothness and silence, ensures a continuing and growing market from automobile connoisseurs.
The Mark II was announced in October 1969, revised frontal styling and vented disc brakes. The Mark III of 1971 had revised seats, fully-cast alloy wheels plus some other improvements. The Mark III was divided to G-, H-, J-series and 'S4-series', depending on the production years. The 'S4-series' version of Interceptor III was the most luxurious Jensen built.
