I don't have two 6th-generation Camaros, however, I do have two cars from Chevrolet's Performance line. Does that count?
Choosing which car to drive is dependent on my mood and the weather. A nice sunny day usually brings out the Corvette because it's a convertible and I do enjoy top-down driving. If I'm in the mood for some aggressive acceleration, hearing supercharger whine, and rowing gears, the ZL1 gets the nod.
The hardest part of owning two performance cars is not which one to drive but keeping them both clean, especially the ZL1. I find myself spending a lot of time standing in my driveway with a pressure washer and foam cannon. Real-world problems, I know.
BTW, my daily is a GMC pickup.
