Since its introduction in the early 60’s, the Ford Mustang has experienced periods of highs and periods of lows. The good thing about the Mustang is that Ford has never taken its eyes off this iconic car. It is a testament to good old-fashioned engineering backed by powerful engine muscle. There have been many variations of the Ford Mustang during the years, and we’ll have a look at a few that seemed more special than the others.
