Historically I was always a Ford fan. I had all Fords until I acquired a BMW many years ago. My wife had always loved Jaguar cars. They were beautiful, however, in the 1980's they were one of them most unreliable cars on the road. British Layland pretty much destroyed the brand during this period and even today many people love the looks of the car but still remember the Jaguars of those years.
In 1989 Ford purchased Jaguar and began resurrecting it. This took a long time as Jaguar was in bad shape at the time. I bought my first Jaguar in 2000. It was a 1994 XJ12. We had a Ford Crown Victoria at the time and it had over 250k miles on it. It was time to upgrade. We looked at replacing it with another Crown Vic but when we saw the XJ12 for sale nearby we thought, what the heck. We always wanted a Jag so now is the time. I got the car cheap. It was under $14k for a car that was originally over $70k.
For a while I owned both the XJ12 and a 1998 XJR. The XJR was a fantastic car for its day. Very quick and fast. Compared to the XJ12, and most other cars actually, it drove like a sports car. I seriously considered taking this car to the track.
While the XJR was great in my book, my wife preferred a larger car with a smoother ride. The XJR had firm suspension and wide tires for great handling. She never used these features though. So we bought a 2007 XJ8L.
In 2004 Jaguar created the X350 body style of the XJ which was all aluminum. This reduced the cars weight considerably. The whole car was redesigned and improved. It was also larger. The XJ8L is the long wheelbase version so it is even larger. The back seat has enormous legroom. It also has air ride suspension with active shocks. Our 2007 was the last of the X350 (2008 was a slightly altered X351).
I also bought an X-Type.
So, why to we love these cars. It is actually hard to explain to people. Each time we were ready to replace our Jaguar, we drove many other cars and always came back to Jaguar. They have a particular feel that is hard to describe. The controls are simple and intuitive. The ride is really fantastic. Not the boaty ride of years ago. Firm yet compliant. The car does not lean in corners yet it can soften up our nasty Illinois roads. Acceleration is very good and smooth. The XJR and XJ8L have a very pleasing exhaust note yet no drone. People are amazed to hear the fuel economy this 2007 XJ8L gets. I have done as good as 32 on the highway. I always get 27 - 32 on the highway, and about 20-22 in town. For a car this huge I feel very good about that. The car just glides down the highway, even on terrible roads. It is very controlled even at high speeds and the driver feels confident going fast. The occupants are in a serene environment even when it is not so serene outside.
Jaguar has actually won or scored very well in several JD power's awards more recently. Both the quality awards and the APEAL awards.
I do all my own work on all my cars. Jaguars are not that hard to work on.
