In its last year, the S-Type Jaguar comes in three varieties: the 3.0, the 4.2, and the R. All are well equipped, and most of the top options are available on the base 3.0 as well.
Even before you check an option box, you should know the Jaguar S-Type 3.0 includes the same top-of-the-line six-speed automatic transmission as the larger models, 18-inch alloy wheels, heated front seats and side mirrors, power tilt and telescopic steering wheel, automatic headlamps, heated 16-way power driver's seat, and rain-sensing wipers. Edmunds says the standard S-Type has been "well-received for its supple leather."
Also standard equipment on the Jaguar 2008 4.2 and R models are xenon headlights and a sunshade. The latter is listed as one of Kelley Blue Book's favorite standard features on the 2008 Jaguar S-Type, leading them to note that "with a press of the button [it] lowers to block direct sunlight."
Although every 2008 Jaguar S-Type comes well equipped, more options are available. Purchasers of the 3.0 can buy the xenon headlights and front park control that come on the 4.2 and the R; 19-inch wheel upgrades are available for the Jaguar S-Type 3.0 and 4.2 as well. ForbesAutos praises the adjustable brake and accelerator pedals, which are optional in the 3.0 but standard on the 4.2 and R.
The 2008 Jaguar flagship of the S-Type is the high-performance R. Along with the improved supercharged engine, there are some R-specific options that Kelley Blue Book finds notable. New for 2008, a special two-tone interior and adaptive cruise control are offered by Jaguar for the R. The lithe Jaguar S-Type R is also available with a special suspension described by Edmunds as a "Sport-tuned suspension with Computer Active Suspension Technology (CATS) that automatically switches between two shock absorber settings to benefit both ride and handling." This option, which Kelley Blue Book characterizes as "worthy of praise," also includes bigger wheels.
