Yeah, the quality went down from what I hear, once Ford bits starting appearing. A friend of mine owned Jaguars (and Volvo's*) back in the day, i.e. 70's when she was rich, aka married to a doctor and running his practice. She said the joke about needing the mechanic first and then buying the Jaguar was true. I rode in a recent Jaguar sedan a while back, it really did feel special, not quite like a Bentley, but close - coolest thing was the flap over the dash vents that closed when the car was off. Must be a similar feeling to the original 60's "personal luxury" cars, i.e. Thunderbird, Toronado, etc.
*They were driving along and the gear shift lever came up and out. Most people would have pulled over with the clutch in. But no, they fixed it while underway with a big wrench!
I got lucky with my 850 - I was on a quest for one with a stick and most of them were ratty and beat up with torn up interiors (even the successor models were tatty, especially the leather interiors - so where the SAAB's). My other choice would've been an early aughts Civic Si like my cousin has.
