The Cadillac CTS is a luxury car, manufactured and marketed by General Motors from 2003 until 2019 across three generations.

A luxury car is a car that provides above-average to high-end levels of comfort, features, and equipment. Often more expensive materials and surface finishes are used, and buyers expect better build quality. The usually higher pricing and more upscale appearance is often associated with higher social status of the users, compared to low and mid-market segment cars.
