1975 Jensen Interceptor Convertible Mk III s/n 1736. S4 model, the last of the Interceptor convertibles, built in August 1975 and features the very late leather-trimmed dash with a walnut face and center console. It also features cast alloy wheels, an electric-hydraulic power top and rear windows, electric door windows, reclining front seats, power steering, air conditioning, a wood-rimmed steering wheel, a stereo with twin speakers, reversing lights and an electric clock, every possible option ever offered on the Interceptor convertibles.

The 440 Chrysler engine has been fully rebuilt and fitted with aluminum cylinder heads, an aluminum intake manifold, steel billet rods and a forged crank. The engine was over-bored to 451 C.I.D. and completely rebuilt, balanced and blue printed and then dyno tested producing 483.7 ft lbs of torque @ 3,500 rpm and 367.0 hp @ 4,700 rpm. The TorqueFlite automatic transmission was also rebuilt. Extremely nice dark-blue-metallic paint over a very straight body, excellent chrome and excellent black leather with a black canvas top. Fitted with a Becker Mexico radio and complete with the original owner’s handbook and workshop manual. Also fitted with 17″ wheels that duplicate the original wheels with Continental Sport Contact 235/50 ZR 17 tires. Includes the original 15″ factory-supplied cast alloy wheels and tires.
