When the first Pro Touring cars hit the scene in the 1990s, the idea was simple. Take the timeless style of a vintage Muscle Car and make it perform like a modern machine. Not only was a Pro Touring car built to be an all around performer, it was also built to eat up miles without breaking a sweat – whether it was a long interstate run or a backroad romp. At some point though, Pro Touring cars may have jumped the shark.
