1984 Jaguar XJS 5.7 V12 from North America
Was a pain, but is now reliable
When I got the car, the owner had just put a new gas tank in, because it was leaking, so it had a gas smell, but I took it out with a mix of putting charcoal and a couple of apples in the trunk.
Also when I got the car, the radio did not work well. The tape player was messed up, and the preset buttons stuck. So after three months of dealing with this, I pulled it out and installed a Pioneer Premier radio, which cost $360 with a five year warranty for the radio. Along the line, I installed a Jensen 600 watt HLX amp with four SPL 6X9's and one Infinity Lappa Perfect 12' sub woofer.
About eight months after I had the car, something went wrong with a valve or a cylinder, which no one knew what was wrong. Not even the Jaguar shop, and my dad, being a trustworthy person, believed them on many things, and ended up wasting about $1600 on trying to fix this engine. In turn, I got angry and pulled the car out of the shop, and took it down to my grandpa's, since he has about every tool imaginable, and pulled the engine out (note to all who decide to do this; you will find your Jag engine has more junk than most Buick's, and are about as tight as a diesel to get out; suggestion, have a lot of patience, and with a few cuss words here and there, you've got it made) and with the purchase of a conversion kit for $1500, I put a Chevy 350 engine in the car, and it works properly now.
Now it's nine months, and I'm starting to think the speakers in my car are messed up and are wearing out, so again I will be installing new speakers soon.
The car was fast, but now it is faster. Plus it still steers like a dream.
The old engine, I sold to someone who wanted to use it as parts, so I have a little bit of cash in my pocket, and I'm happy to get rid of the engine, and I'm thinking about upgrading my amplifier to a Memphis Belle one of these days.
I never liked the backseat; no room at all. My fiancee can't even fit back there, and she is petite, but hey, fixes the problem with the sub woofer, and other speakers that you can't put in the trunk due to the gas tank, so what I did was put my sub between the driver and passenger seat, and mounted the four 6X9's onto the sub box, and ran the wires from the amp in the trunk to the speakers in the backseat.
Also, about the new engine I put in it; could I get a few words on what to put on it to make it faster? I'm getting different opinions on this.
Would you buy another car from this manufacturer? Yes

What a shame you have destroyed a lovely british classic by messing about with stereo systems and sticking an american engine in it. You appear more concerned with the amount of power the boogie box kicks out than the engine. Please do not get me wrong, I am a big fan of American cars and their big V8s, but feel that transplanting these engines into a jag negates the whole point of having one, why not just buy a mustang or something?
I have an early XJS (1979) V12 which has never given any mechanical trouble - although the electrics are as usual full of gremlins. The engine in this pulls like a train, is quiet and smooth, if a little thirsty and has the potential to tune to racing car spec (TWR got 700BHP plus out of their 6Litres)
Anyway, enjoy your jag, at least it will be cheaper to service and repair now! (and it won't break)
