Jaguar is a complete disappointment, with a lack of outstanding and distinctive product.
I got to drive an XJ8 in the late 1990s and found it to be a nice, competent car. From what I have heard, the reliability was good as well. It appeared that Ford had made a good thing out of Jaguar.
Then the bean counters came in. We got the S-type based on a Ford platform. It wasn't too bad, however, feeling a lot more like a Jag than a DEW98 Ford (LIncoln LS).
The worst thing that has happened to the Jaguar has been the X-type, which is a Ford Contour in a Kitty Costume and the redesigned XJ8.
All Jaguars have speed governors which restrict them to 121 mph for the lower performance models and the requisite 155 mph for the R-type models.
Sir William Lyons would be spinning in his grave if he saw what has become of his company. The motto: Grace, Space and Pace has been thrown in the corporate trashbin. Shame on whoever is responsible.
