The Shelby is a higher performance variant of the Ford Mustang. The Shelby nameplate was revived in 2007 for new high performance versions of the Mustang but this time designed and built by Ford at Ford Plants.
I must be in a Mustang mood. I bought this Shelby 500KR built and have spent the past week adding some extra detailing and wax.
Just a shot to compare the front ends on the older Mustang (left) and the 2015 Mustang (right).
