to T-tops, plus a fabric rear section including the rear window; there was an optional hard top for the rear section. Approximately 1598 Right Hand Drive and 3416 Left Hand Drive cars built. Some cars were converted by the factory to from RHD to LHD and LHD to RHD for factory experimental use and ultimately to be shipped to the target country and some were dismantled. Whilst there are a small number of the XJ-SC cars with the rear seat conversion. Jaguar Cars only ever produced one such car which was specially built for Princess Diana. The rear roof section on this car was fully secured in place and could not be removed. This conversion was later carried out by several aftermarket companies on owners cars, not with the approval of the works. There were several specials built as there were for other XJS cars, the Princess Diana Cabriolet and there is a very rare Guy Salmon Jubilee Celebration car, only 3 believed to be built a Burberry Special Edition also believed to be only 3 produced.

To accommodate this design element, the Hess & Eisenhardt convertibles have two separate fuel tanks, positioned to allow for the roof to fully retract. The process of converting the stock Jaguar XJS coupé into the H&E Convertible included the post-production removal of the roof, cutting the body in several sections, the addition of steel reinforcements behind the driver's seat, and weights placed just behind the headlights to eliminate harmonic resonance caused by the significant modifications to the car. H&E XJS convertibles are easily identified by the lower folding top, as well as two small badges located just behind the front wheels.
