The Jensen Healey and Jensen GT were built by Jensen Motors Ltd. of West Bromwich, England from March 1972 until May 1976. A little over 10,000 convertibles were manufactured during this time. Some of the last Jensens to roll out the doors were the Jensen GT ('76 model year) of which a scant 509 were produced. All Jensen Healey and Jensen GT automobiles came equipped with the brand-new 2 litre, 16-valve Lotus built 907 engine. Home market and European destination cars had twin 40mm Dellorto carburetors while U.S. Federal destination cars came with twin Stromberg carburetors. Jensen Motors numbered the JH starting at 10000 in 1972. 10000-13349 are Mark I cars. 13500-20504 are Mark II cars. 18900 + VINs also have the JH-5s mixed in. Jensen GT numbers started at 30000 in September '75.

The Jensen Healey debuts in March '72. Original cars have a simple but pleasant interior; plastic center console, no wood on dash board (72 only) or wood on glove box, rubber floor mats, black interiors (a few early cars are seen with tan interior) and square-cornered headlight cowls distinguish these models. Very early cars will have the noteable absence of a passenger side door lock (quickly added on the '73 model year) and auxillary oil filler canister mounted to firewall in engine compartment. Some early cars have no oil cooler as well.
