Cadillac is sharpening the style of its ATS range with a pair of packages that adds some darkened elements on the exteriors of the cars as well as some extra luxuries inside. The packages, labeled the Midnight and Black Sport, are available now on the 2015 ATS and 2015 ATS Coupe, with prices starting as low as $600.

The Midnight package adds things like black chrome accents on the grille, window moldings and standard 18-inch wheels. For the interior, the package adds suede trim and the Cold Weather Package, which includes a heated steering wheel as well as heated front seats.
