car collection: The Ford Shelby GT500 is the most powerful Mustang

The Ford Shelby GT500 is the most powerful Mustang on the road today and arguably one of the most successful projects from Ford's Special Vehicle Team (SVT) in terms of performance, excitement and, importantly, quality.

In fact, early indicators show the Shelby GT500 is a quality standout. In the most recent Global Quality Research System (GQRS) study from RDA Group, an independent research company based in Bloomfield Hills, Mi., the Shelby GT500 earned praise as the highest-quality Mustang model, with the fewest "things gone wrong" in the first three months of ownership.
