What type of convertible car top is best?

The 1981 XJ-S received the new High-Efficiency engine for much better economy. The XJ-S was also now the fastest automatic-transmission car in the world at 155 mph. In 1982, the new V12 XJ-S won first and second at the Tourist Trophy race at Silverstone. In 1983 a new cabriolet version débuted with a new 3.6-litre Jaguar AJ6 engine, the XJ-SC. In the XJ-SC, the rear jump seats were eliminated making it only a 2-seat car. The XJ-SC was not a full convertable but had a non-removable center targa-type structure and fixed cant rails above the doors. The rear quarter windows remained as well. With the introduction of the AJ6 engine in the XJS chassis came the availability of a 5-speed manual transmission for the 6 cylinder cars. This model with a Getrag manual transmission was not imported by Jaguar into the United states. A limited number of 5-speed AJ6 cars did enter the US as grey market personal imports however. A V12 XJ-SC did not emerge until 1985. The two-seat XJ-SC targa-type model was replaced with a two-seat full convertible in 1988. Prior to that there was a special full convertable version called a Hess & Eisenhardt XJS offered through dealers starting in 1986. The Hess & Eisenhardt coachbuilding firm was located in Ohio and built approximately 2100 of these cars under contract from Jaguar before the official Jaguar built XJS convertible appeared in 1988 to be offered as a 1989 model. The Hess & Eisenhardt convertible differed from the later Jaguar convertible XJS as it's unpadded top folded down deeper into the body structure of the car resulting in a cleaner rear profile when the roof was lowered. The later Jaguar full convertible had a heavier padded top that did not fold into as small of a bundle when in the lowered position.
