Seats are refreshingly supportive, for a Cadillac, without being overly firm. Arm rests and head restraints are a degree or two softer than the cushions and side bolsters, boosting the comfort factor a couple notches. All essential controls are within easy reach, although there could be more clearance between the lower door panels and seat bottom to access the front seat adjusters. For this reason, we were especially grateful for the seat memory feature, which often saved us from having to reach down there. The interior is roomy, fitting in between the marginally smaller CTS and externally larger 2003 Seville.

Instruments are easily scanned, white-on-black round analogs, with a large nested tachometer and speedometer between the smaller fuel and engine temperature gauges. The speedometer changes between English and metric electronically, so there's only one set of numbers around its circumference. Cruise control and running lights are managed via a stalk on the left side of the steering column, windshield wipers and washers with a stalk on the right. Buttons in the steering wheel spokes provide redundant controls for audio and driver information functions. A word of caution: the top-level stereo system, although delivering superb surround sound, is multi-tasked with a navigation system that, in combination, demands an extensive study of the owner's manual to operate with any degree of alacrity and confidence.

All four doors boast map pockets. The front center console is deep and wide and pre-wired for cellular and Bluetooth (to wirelessly tie the cell phone into the car's audio system allowing hand-free operation). The glove box, though, is barely sufficient to hold the navigation DVD case and owner's manual. Two cup holders are provided front and rear. The trunk is fully lined, with articulated, gas-pressurized struts.

Fit and finish are top grade, with notably tight interior trim tolerances. Careful attention was paid to reducing noise, vibration and harshness, with remarkable and commendable success. Specially laminated windshield and front door glass, wind tunnel-tuned outside mirrors and high-density/low-mass sound-deadening padding combine to deliver the quietest interior Cadillac's delivered in memory.
