A couple of nits: The 18-cubic-foot trunk looks impressive, but the opening is pinched by the sloping back window and much of the space is under this rear window, so upright items can be problematic. At least Cadillac provides 60/40 split folding rear seatbacks so tall things can slide through on their sides.
And, the glovebox lid in the test car always looked like it was ajar and crooked on the right side, even when it was latched.
A word of caution: The bright-colored multi displays in the XTS can be distracting, and less-than-immediate response to touches of the Cue display screen can make early working of Cue confusing.
And turned off, the display screen shows off all the fingerprints it collected.
More than 12,600 XTS cars were recalled in October because, after folding forward, the rear-seat head restraints might not lock in place in the upright position. This could result in a neck injury in a crash.
