Especially in black or Thunder Gray, this one's bad to the bone. Stylish five years ago, behind the times today. Each CTS body style's exterior polarizes opinions. I'm a fan. Supercharger on top, but the engine itself is covered up. Black Diamond Edition combined black metallic paint with black wheels and yellow brake calipers. The V can be identified by its large mesh upper and lower grilles. No minivan substitute, but it'll do for even large grocery runs. Note handy partition. Plain by current standards. Big change coming.
