18. Cadillac XTS
Complex Says: Cadillac has been all about big-ass luxury sedans for the better part of a century. The outgoing DTS and STS were, however, uninspired pieces of blah. With the new XTS, Cadillac is hoping to rekindle the flame that makes Americans want to buy big, buy expensive, buy luxurious, and buy American. The XTS is the kind of car we have always liked here, so let's hope that Caddy can stick it to ze Germans.
