If you were serious about driving a Jag during the easy-money 1980s, you needed the optional wire wheels. That showed those rubes in the BMW 735s and Mercedes-Benz 500SELs what real class was all about.
The 4.2-liter version of Jaguar's legendary straight-six engine made 176 horsepower in 1985. That was six fewer than the 735i's six and eight fewer than the 500SEL's V8. However, the XJ6 cost $32,250, versus $36,880 for the BMW and $51,200 for the Benz. Given that the Jag offered at least as much (and maybe more) status on the street, its price tag looks like a pretty good deal.
Of course, the electrical stuff would have a few issues, but so what?
