First I'm new to Jaguar, just joined the forum and I have a newbie dumb question.The car I just bought is a standard 2008 XJ8. How do I know if it is a X350 or a X358? I have the original MSRP window sticker and it does not make reference to any model numbers.

 

Hi and welcome. The08 is the 350. They are from 03 to 10. The 358 is the style from 10 till now.

Thanks Leovt. I googled it and got conflicting information. One site said one thing, another said something else.

 

350- 2003-2006

358- 2007

S*N*G BARRATT catalog says

 

Oops. Your right . No changes 2996 2010 models are 351

For the North American market, my understanding is:

X350 through 2007

X358 for 2008 and 2009 (with the lion’s share of the ‘09 badged units actually produced in ‘08) Distinguished by the vertical vents just aft of the front wheels, and also redesigned grill/bumper.

XJ hiatus for 2010

X351 commencing in 2011

 

You guys are making me crazy....so my 2008 (Two thousand and eight) is a X358, right?

 

2008 is a 358.

One easy way to tell the difference is that the 358 has the direction indicator side repeaters up in the door mirror casings whereas the 350 has them down in the front side bumpers (fenders).

 

The 2003-2007 USA model years are x350. The 2008-2010 (hence x35_8_) are the facelifted models. Post-2010 is the x351 chassis.

 

First paragraph in the introduction of the catalog is what my statement was based on
Front of the catalog Classic & Modern Jaguars 350/358

 

The X350 was updated in the 2005 model run. The result is the X356. This was run to the X358 change.
Several changes to engine, and control modules.
The X350 was higher volume sales in the US.

 

Your photo shows the car as an X358. This had a different front and rear bumper style plus a few other bits and bobs. The current XJ is the X351; confusing isn't it ! I had an X350 2010-2016 and an X358 2016-2019. I preferred the earlier styling, but the later cars are better as Jaguar mostly sorted out all the issues, except for the short life of the suspension bushes. This design also went into the Lincoln LS. The problem bushes are : -

- Bottom bushes of the air spring units. Rears easy to replace, fronts can be difficult as they're mounted in the wishbone arm.
- Front lower trunnion bushes of the front wishbones
- Bushes in the rear lower wishbone arms
- Rear tracking arm ball joints
The upper wishbones front and back have a much longer life, and thank goodness as they are expensive !

OK, so that settles it.....I have a X358. Thanks for the help.

 

I have a 2008 X358 (XJ6). I think the X358 is 2007+ (a minor facelift whilst we waited to be disappointed by the X351)

Quickest way to tell when browsing ads, is the (older) X350 has bumper chrome inserts, or the X358 has false air vents on the front fender.

You can't really tell by the grill because people change them. Originally, the X350 should be horizontal and vertical slats (unless it's an XJR), and the X358 should be cross-hatch pattern.

I own an X358 only because it was the latest year I could get for this model. Other than that the upgrades X358 vs X350 appear to be mainly "bling", not all of which I agree with but never mind. Self-criticism to keep my X350 brothers happy lol. (lol? Lots Of Love)

 

The FALSE AIR VENTS SUCK, look nice enough, if only they worked.

 

At least they could have connected a hose between the air vent and the ashtray so the ashtray would be self-cleaning.
(except in Australia and California)

 

What happens when you back up?

 

Uh...reverse speed is not fast enough to outrun a fire...not even in a Jag.

Anyway, the false air vents are seriously silly, but appear on most current Jags (and some other cars). It appears that, for Jaguar, our beloved X350 was used as a testing ground in the X358 for them. I can only imagine they imagined it helped sell cars, though the X358 actually had quite low sales numbers probably for other reasons (such as waiting for the X351?)
