As creations of the premium wing of GM, the price of a new Cadillac can seem daunting. But even luxury brands need an everyday choice to get people interested in the brand so that they dole out more cash on the costlier options later on in life. For Caddy, this is the CT5-V. With a starting point of around $47,000, and enough power to earn a spot in the performance category, it holds the title as the most affordable performance option.
