Although these cars have remained very popular with Jaguar owners for the many years since their 1987 introduction (1988 in the US), there is still relatively little aftermarket parts suppport for them. The aftermarket instead concentrated on the earlier (70-87) sedans, and left these alone. That's a shame as these are great cars, with a unique confident, somewhat sporting, and slightly quirky personality all their own. Jaguar Specialties is pleased to offer several different and useful upgrades and conversions for these models, as follows:
