30: Cadillac XTS
What was supposed to be the replacement for the aging V8-powered STS has become nothing more than a shadow of its predecessor. The Cadillac XTS is just about one of the most unknown models to come out of the brand. There’s nothing really special to make the car stand out from the crowd.
Aside from a roomy interior and a slew of optional luxury features, the Cadillac XTS is marred with a high price tag and little in the way of style. That’s why GM has decided to put the big, stately sedan on the chopping block for 2020.
