Interesting comparison in the modern era, the presenter asks the ultimate question: are you going to be on the hwy/interstates or more in the two lane back roads?
In the late 70s/early 80s, in my tweenie years, my dad had both an XJ6 and an XJ12 simultaneously. Both were automatics, the only way they came back then. Today, with both E9 and E3 experience, both 5spds, the comparison is a natural and good one.
I agree that the BMWs are the more engaging 'driver's car' (especially with a manual tranny), but the impression of the Jag's interior and effortless highspeed cruising manners are truly top shelf. The XJ has a different presence and is a wonderful place to cover a long distance: 'grace and pace'.
A Series 1 XJ with a manual tranny and some performance and reliability tweaks, that would be a truly an interesting big 'cat'.
