If you serious about owning this car. You just can't take the owner word for anything. The original asking price is out of the question. I wouldn't give him
more than 4K for the car considering the money you will need to spend to repair it. That gives you 4K to invest in repairs. You will need all of it.
First thing is to have a compression test done and a leak down test. You may need to invest the time to watch this procedure or do it yourself.
My personal tendency is to not trust anyone for their word. When there is money involved. People will forget their morals. If you have any mechanical ability.
Do it yourself. ( A word of caution. If you have no mechanical ability. Don't buy a Jaguar ). These cars need constant attention. You need to be able
to diagnose and repair some of these minor issues. Unless your wealthy. I have six Jags in my driveway, so I have a little experience with them.
I do not have a supercharged Jag and I'm not familiar with how that unit is cooled. Coolant in the oil is a serious issue. Only a few ways that can happen.
Head gasket or cracked block, or maybe a cracked head. You state that coolant was found in the oil. With a bad head gasket, coolant can not just pass
the piston rings and into the crack case unless the rings are bad. I have to presume that the leak is around the oil and coolant passages in the cylinder head.
A compression check may look good and lead you to believe that all is good with the head gasket. I think you need to assume that the heads will need to be
pulled and inspected. This is not a project you can short cut. I would not consider replacing the engine for a used engine either. You may be buying a whole
new set of problems. Either purchase a rebuilt engine or rebuild this one. Otherwise you may end up chasing your own tail.

Worst case scenario, it's still a beautiful body/chassis with nothing else wrong, if you can buy it right, have an LS motor dropped into it and never have to worry about it again. Total cost shouldn't be too bad (don't have a clue what such a conversion would cost where you are though) and yield you an awesome looking and performing car with far better reliability, easier to work on and get parts for if you ever need to. Just a thought.
#27
Yeah, no. Maybe in years past that would be a viable option (coyote would be better), but with all the integrated electronics would make any swap.... problematic. It would cost more than the entire vehicle would be worth.
#28
Not really. The reason I bought it up is because there is a company that specializes in LS/Jag swaps. They already have kits that basically make the swap a bolt in, plug & play. The only thing I'm not sure about is if they have them for X-150's or not but they definitely have kits for X-100's.
#29
Yeah, X100s have like 2% of the integrated electronics of the X150. The TSD is even integrated with the electronics of everything. You'd no doubt lose that and all the vehicle settings and stereo and all that.
You'd end up with a rolling chassis with a crap engine. Wee. Totally destroy a perfectly good car. Good call.

What are the issues on importation? Does it need more than being GCC spec? Certainly an XKR has more going for it. You could consider a 5.0L XK which has similar performance to the 4.2 XKR, but a little tidier interior and few other detail differences.
I am amazed at how low prices drop on older cars in the Gulf in general.

And yea, European cars prices drop like crazy in here (couple of days ago I found a Porsche Cayman S 2008 with 45K miles on it with only $5,000 - Maybe because European cars can not withstand the harsh environment of the Gulf area (in Summer, the temp exceeds 120F easily, so a lot of European cars breakdown or the AC would not work)
They prefer American cars (a 2007 Mustang 5.0 in a decent condition worth much more than a 2007 Jag)

Thank you all very much for your valuable feedback.
I've taken the car for inspection, and the motor gave around 8 errors (including 4 oxygen sensors needs replacing, along with issues with supercharge air intake, catalytic converter damaged and some error in the ECU).
The water was missing one third in the radiator, and the owner refused to perform a compression test (he does not want anyone to mess with his car !!).
Overall, the mechanic told me no way this is a low mileage vehicle and he suspect that the owner has manipulated the meter.
In addition, when I paid attention to interior, both trunk and hood hydraulics are broken (one is even missing in the hood), gloves compartment in broken, etc.
So unfortunately I have walked away from the purchase as repairs only would cost more than the car itself if its in a decent condition by far.
Thanks again guys, and hopefully I would find another one where I live (which I suspect they exist), otherwise, i'll go for a 5.0L XK
