Cadillac XTS 
Since the advent of the CT6, the future of the Cadillac XTS is in doubt. These full-size luxury sedans overlap one another in the lineup. The XTS remains available, however, and it even gets a few cosmetic improvements for 2018! It comes with a 304-horsepower, 3.6L V6, although those who want even more power will opt for the V-Sport trim level and its 410 horsepower, twin-turbo V6 engine.
Pros
- Roomy cabin and trunk
- Comfortable ride
- Lovely colour schemes
- Good engines
- Afforable pricing
Cons
- CUE infotainment system needs improvement
- Fuel consumption (especially the V6 twin-turbo)
- Perceived as a commercial vehicle
- Questionable plastics used in cabin
- Middle seat in rear is uncomfortable
