The Cadillac has gone through an evolution over the course of the last few years, suffering from an identity crisis that led the company to create the ATS and CTS series, which removes all the glitz and glam and offers up a sedan and coupe that could rival BMW. While the car is top-of-the-line, the radical departure from previous Cadillac models has left the ATS with very little to show for it.
