When the folks at Cadillac put the three-row-SUV XT6 Premium on my agenda a few weeks ago I wasn't sure what to think except that it is probably popular with the folks that need a mini-van but don't want the stigma. Let's face it, three-row SUVs are hugely popular and practical if you have a family but I've never once experienced one that was enjoyable to drive and made you smile while approaching it in the garage. That is, until now. The moment I first tapped the accelerator when leaving my garage I realized this was not merely an upbadged Traverse.
