19. Cadillac CT6

The Cadillac CT6 is engineered for luxury road trips, offering an impressively roomy cabin and magnetic ride control that adapts instantly to changing road surfaces.
Passengers will love the available massaging seats, which help melt away fatigue on longer drives. Note that the CT6 was discontinued in the U.S. after the 2020 model year, but it remains a sought-after choice on the used luxury market for its blend of American comfort and technology.
