The leather seats are excellent, comfortable for all-day driving with good bolstering to hold your torso in place in sharp corners. There's good support for the driver's right leg, and where the right shin touches it feels soft. There's a good support for the left leg as well, with a good dead pedal for the left foot.
The three-spoke steering wheel contains buttons for the sound system and cruise control, and is deliciously padded in leather for all but the part of the rim between about 10 o'clock and 2 o'clock, which is trimmed in wood.
Changing the temperature, adjusting the stereo, and operating the navigation system are easy and convenient in the CTS. The center stack juts out from the rest of the dash, with the elaborate GPS navigation system at the top center location. Climate controls are at the bottom, controlled by amber-lighted pictograms.
The stereo works well, allowing quick and easy switching from a news channel on XM Satellite Radio to music on FM to traffic on AM to a CD. The small triangular speakers for the optional Bose system are mounted on the A pillar, and look cool. OnStar is provided, allowing drivers to make hands-free, voice-activated calls. OnStar operators will call out the emergency crews if the airbags go off and you don't respond, they can unlock the doors for you, or direct you to the nearest gas station, ATM or Italian restaurant.
The CTS offers more interior room than some of its European competition. A tall driver or passenger will be comfortable in front and only slightly cramped in the rear. The rear seats are comfortable for two or three passengers, offering good leg room, though lacking in thigh support. There is a convenient pass-thru tunnel between the rear seats, to the trunk, if the split folding rear seats are ordered.
