If your idea of a Cadillac is a plush-riding luxo-barge, then the XTS is the Cadillac for you. With a 305-hp V-6 and front- or all-wheel drive, it’s perfect for the senior citizen in us all—or for real senior citizens. Need more? The Vsport has a 410-hp twin-turbo V-6 and all-wheel drive. While the XTS is competent, not even the Vsport is much fun to drive. Other than the fussy CUE system, the interior is terrific, with excellent materials and a big back seat—the better to be driven in, yes?
