The Mk II was announced in October 1969, revised frontal styling and vented disc brakes. The Mk III of 1971 had revised seats, fully-cast alloy wheels plus some other improvements. The Mk III was divided to G-, H- and J-series, depending on the production years. The "J" version of Interceptor III was the most luxurious Jensen built. Total production Series I, II and III 1966 to 1976: 6408, LHD and RHD.
Jensen were one of the first manufacturers to equip a production car with four-wheel drive, in the shape of the 1967 Jensen FF (Ferguson Formula). At the time it was hailed as a remarkable development, coming also with anti-lock brakes and traction control. The car was four inches (100 mm) longer than a 'standard' Interceptor, with the addition of two side vents on the front flanks. Press from the time quote "drag-strip" performance when describing the car. 320 Mk I, 109 Mk II and 15 Mk III FFs were made
A convertible with powered soft top was introduced in 1974 mainly intended for the American market but also sold in Europe. 267 convertibles were made.
Rarer still is the Coupe version with just 60 made[1], derived from the convertible and introduced in 1975, just a year before the company's demise. It could be said though this version detracted from the rakish, stylish looks of the GT.
