There are well documented, long-term issues with the XK8 that should have been addressed in a car that is 20 years old. Regularly maintained at dealers over the years, with a few exceptions, all these have been attended to in my car. My car has the original nikasil-bored engine; high sulphur fuel has never really been a problem in the USA. My main maintenance problem has been the reliability of the air conditioning system with most of the system being replaced over the years. The car has never let me down on the road. It was my daily driver when I was still working - all year-round. Snow and ice were a challenge without snow tires and no weight in the boot. The Harmon Kardon sound system is superb. The XK8 convertible is a pleasure to drive and, even given its age, still turns heads. I will never regret buying it.
The feeling you get driving this car is unsurpassed by any other vehicle I have owned. It is now a 15 year old car but it still turns heads. I picked mine up from the original owner for less than 25% of the sticker price. Problems associated with this car can be remedied for a small price if you can do some of the work yourself. example: cam chain tensioners can be replaced with common hand tools for less than $250. With care and maintenance this car can last for many years to come and is a blast to drive
I purchased as a second owner... Love the car, it's pure white with tan interior. I have to say that this car gives you a different feeling than any other. I have had many convertibles but none compare to the XK8 and performance.
That you can manual shift at any given time when your battling traffic or just want to fly down the road. It hugs the road very well.
Interior could be better put together. The quality is there, I would have just expected it to be a better built.
Do a web search for secondary timing chain tensioners and you'll read about what happened to my car at 58,000 miles. If I didn't have an extended warranty to pick up the tab for the month long rental car and ~$8000 worth of engine replacement work, this would've been a total nightmare instead of just a bad dream. Look elsewhere unless you want a car that will get you looks as well as get you stranded.
Foglights helped with vision because headlights are too dim. Leather boot helped protect the canvas convertible top from flapping with the top down.
Opening the driver door from within after the top gets wet resulted in water dripping from where the convertible top met the front windshield frame. This was how the car was designed and made for wet trousers/seats/floormats any time it rained. Also, the antenna looked like a flagpole.
