I love driving this car. However, it is very important to read the books that come with the vehicle so you will know what to do if you have problems. Some things you and repair yourself. Unlike other vehicles, the parts under the hood are fairly visible making it easier to work with should you need a repair. I love it. Great for a retired person who drives around town at his/her leisure. I would not recommend it for someone who has to commute everyday. I will burn a lot of gas and you will have to add oil every 2 to 3 weeks.
Purchased from original owner, low mileage. Beautiful car, best ride ever IF you can keep it out of the shop. Never could get the heater to work properly, froze every winter. Difficult time finding a "good" jaguar mechanic that could troubleshoot. It seemed to always be something. Every time it went to the shop it was $600-$1000. The final straw was when the transmission went out at 79K. Resale value was so low I chose to not fix the car. What a shame. I'll never buy another one.
I have owned and driven, Cadillacs, Lincoln Continentals, Mercedes Benz and Porsche. Although these are all fine vehicles, the Jaguar XJ8 is the most complete as far as reliability, comfort, ease of driving and maintenance.
