I was reading on another website today and it said the X300 LWB is known as the X330. I never new that

Yup, but since this knowledge is so few, most everyone still says X300 LWB. Of course, those with the X305 (Xj12), and X306 (Xj6R) can still use the X notation.

WOW, I have just learnt that thanks to your input lol
I think it's a good idea to make a FAQ related to these codes

Sounds like a job for a SUPER MOD

LOL, thanks I just updated the content

I seem to remember the X305 and X306, too; but I'm having a devil of a time substantiating them.

There are several designations that are seldom referred to. They just get lumped in with the original model.

Edit: Kudos to TopHatChef, he caught me overlooking a type-o. I found it where it is correct for the X300. The image is fixed.

Cheers,

That is a very interesting and wrong photo attached. Where it first mentions the 1995-1997 cars, it says the Xj8-XjR as X300 (should be Xj6), and later 1998-2003 Xj8-XjR as X308. I'm curious to know if its wrong anywhere else, or if it's just the one type-o. They also seem to have forgotten the X305 and 306. I was really hoping that when I saw that photo it would be the definitive answer to knowing the special model numbers.

Thanks for catchin' me nappin'!! I have fixed the image in post #6. I'm still looking for something to substantiate the X305 and X306 in print. Nuttin' yet.

Cheers,

Hi.

I just want to make sure I am calling my model the correct thing. When I bought it the previous owner said 97 XJ6L. Here I was told X300 and at the Jag dealership my work order states Sovereign 406? Are all of these correct?
