As long as you’re sitting in the front seats the 2009 Jaguar XK series coddles its occupants.
Consumer Guide gives kudos to the interior quality of the Jaguar; 2009’s XK has a few plastic pieces that disappoint, but “cabin materials are otherwise high quality and well-assembled. Standard wood or available aluminum trim each creates an inviting ambiance." They give high marks to the standard "steering wheel paddles [that] are easy to use and provide even faster gear changes."
Cars.com says the "front-seat legroom is far better than average and its dimensions are more than workable for adults. The backseat is such only in name. There's no legroom at all unless the front occupants slide forward, and the seat cushions have oddly shaped contours."
TheCarConnection.com found reviewers galore who praise the comfort and luxury of the Jaguar 2009 XK, but almost all disliked the two small backseats. Forbes Auto agrees, noting that "two adults will be cozy in the nicely trimmed, two-seat cabin; like most low-to-the-ground convertibles, however, getting in and out with the top up can be a problem." On the bright side, you don't have to get out to deal with the top, as it’s a fuss-free power arrangement.
