The 2015 Cadillac CTS boasts the polished appeal of the iconic American luxury brand along with high style, impressive performance and high-tech features. The formula is already working to entice a new generation of buyers to the brand.
If Cadillac’s styling is too edgy, you might prefer the more traditional looks of Euro competitors such as the Audi A6, BMW 5 Series or Mercedes-Benz E-Class. Those brands also offer wagon/hatchback variants for buyers needing extra space, and in the case of Mercedes, a stylish coupe and cabriolet.
