2017 Jaguar XF Seat Room and Comfort: Pros
Year	Comment
2016	And space? The real magic: the new Jaguar XF combines a sleek, sporty body with a usefully roomy and comfortable rear seat. There's more rear knee room than in the BMW 5-Series, and even than in the larger regular wheelbase Jaguar XJ. (For buyers who need even more legroom, Jaguar also offers an extended wheelbase version of the XJ.) If you compare the XF to German cars with at least equally sporty styling, it has a much roomier rear seat. The BMW 6-Series Gran Coupe, though a couple inches longer than the XF, has a cramped, uncomfortably positioned rear seat. The Mercedes CLS does better in its second-generation form, but still doesn't compare to the new XF in this regard. The Cadillac CTS, though its profile is very much that of a sedan, also has a tighter rear seat than the XF. For a combination of coupe-like styling, agile handling, and rear seat room, the new XF can't be beat. But wait, there's more. Even though it retains a spare tire (BMW and Cadillac have tossed theirs), the new XF also has the roomiest trunk in the class--over 19 cubic feet. But the XF isn't offered as a hatchback or wagon. The Audi A7 hatchback remains the versatility champ among sporty midsize luxury cars. The other thing keeping the XF from being the utility champ of its class: the center console storage area is barely there. see full Jaguar XF review

2017 Jaguar XF Seat Room and Comfort: Cons
Year	Comment
	Continuing my interior nitpicking, I'll add that the new Jaguar XF's seats provide acceptable support and comfort, but the seats in some competitors are exceptional. Jaguar lags here. It might help to step up to the 380-horsepower XF S (which actually costs a little less than the tested 340-horsepower R-Sport), as its seats include power adjustments for the side bolsters and cushion length. The rear seat, though usefully roomy, is also on the firm side. On a positive note, the XF's driving position is very good. The instrument panel isn't overly large or imposing, and the windows are reasonably large and are not too steeply raked. Outward visibility is at least as good as that in the BMW 5 Series and much better than in the scrunched down 6 Series Grand Coupe. see full Jaguar XF review

2010 Lexus IS Seat Room and Comfort: Cons
Year	Body/Powertrain	Comment
2010	4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic RWD	Legroom felt narrow for passenger over tranny tunnel. see full Lexus IS review
2010	4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic AWD	Lousey seats: uncomfortable and build is cheap and not conforming to human posture. But, seems last several years most cars have lousey, cheap and uncomfortable seats. see full Lexus IS review
2009	4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic AWD	Cramped rear seat. Minimal knee and leg room when there is a front driver/passenger. Minimal room for the toddler when sitting in a car seat. Seats 2 small kids at best. see full Lexus IS review
2009	4dr Sedan 306-horsepower 3.5L V6 6-speed shiftable automatic RWD	This is a small car. Interior seating is comfortable but tight. Unless the driver is very short, forget about the back seat. see full Lexus IS review
2009	4dr Sedan 306-horsepower 3.5L V6 6-speed shiftable automatic RWD	Don't buy this car if you ever plan on carrying four adults. see full Lexus IS review
2009	4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic RWD	Yeah, the back is small but still big enough to handle for the poor rear seat passengers. see full Lexus IS review
