All XJs feature polished burl walnut trim and contrasting piping on the leather seats. Some have soft, long-pile wool rugs in the footwells, which make you want to ride with your shoes and socks off (even if those rugs are harder to brush off or clean). The walnut in the Vanden Plas and Super V8 is hand inlaid with chunks Peruvian boxwood, and a lighter elm trim is offered on all models at no cost.

The XJ dashboard sweeps across the front of the cabin in a fairly high position. Three primary gauges are clustered in front of the steering wheel, with the speedometer slightly larger in the center, tach to the left and fuel and temperature gauges combined on the right. The center stack features a seven-inch LCD touch screen for managing climate, audio and navigation functions. Jaguar has made the controls easy to operate and avoided the temptation to include a host of gee-whiz computer controls. We find the control center in general, and the touch-screen navigation system in particular, far preferable to the point-and-click devices in German competitors.

While the XJ is a large car, everything adjusts to accommodate drivers from tiny to almost huge. All seats feature sixteen-way adjustment, and foot pedals can be moved up to 2.5 inches at the touch of a switch. The XJR and Super V8 feature more heavily bolstered sport seats. We'd recommend them to drivers who like the occasional blast down a canyon road, but the standard seats are just fine.

The current XJs are roomier than ever. Gone are the days when the unmistakable Jaguar styling brought an obvious (obviously cramped) payback inside, compared to German cars. While the long-wheelbase versions have proven popular with American consumers, they were originally developed for Europe's chauffeur-driven executive class. Five extra inches in the car's length is entirely behind the B-pillars (between the front and rear doors), so inside it means a lot more rear seat room.

The rear seatbacks also recline, and there's a switch provided for the person riding in the right-rear seat to power the front passenger's seat forward. This allows plenty of room to stretch out and enjoy such things such as wooden picnic trays that flip down from the backs of the front seats. The Super V8 comes standard with separate climate controls for each side in back, as well as the dual-screen DVD entertainment system. The 6.5-inch LCD monitors are embedded in the back of the front-seat headrests, with a control panel located in the rear center armrest that operates the screens independently. One person can be watching a DVD while the other plays a video game or looks at snapshots from a camera.

The XJ's trunk offers 16.6 cubic feet of volume, which is more than the Audi A8 (14.6 cubic feet) and BMW 7 Series (16.3), but less than the Lexus LS460 or Mercedes S-Class (both 18.0). To be sure, we wouldn't expect buyers in this league to choose primarily on trunk size, and the XJ's trunk is large in any case. It will swallow lots of luggage, and at least a couple really large golf bags.
