The Ford Mustang has gone through multiple styling changes in the 50 years it has been on the market and there are times when the muscle car’s classic look is still preferred. That being said, try finding a 60’s Mustang in excellent condition that some old timer doesn’t have bubble-wrapped in his garage. Chances are, you won’t find one at an affordable price. You can look for ages, or just take your brand new 2012 Mustang GT and give it a retro makeover. Twenty-three year old, John Heerman did just that and is bringing his one-off Retro Stang to the 2011 SEMA Auto Show next week.The Ford Mustang GT Retro Stang is modeled after a 1968 Mustang and features a 14\" longer hood and ’68 and ’69 Mustang sheetmetal hand grafted into the nose, tail, and rear quarter panels. The rocker panels are also custom made and the headlights, doors, and rear fender caps were hand built from scratch by Heermann. The exterior transformations also benefited from a raised back glass to give the car a fastback look.Mechanically-speaking, the Retro Stang was equipped with a set of Dynatech long-tube headers and X-Pipe, a JLT cold air-intake, an APR carbon fiber engine cover, and an SCT tune.Sometimes these DIY makeovers can be utter disasters, but when done appropriately, they can turn out to be a true work of art. We’ll see which category this Retro Stang falls into when we check it out at the 2011 SEMA Auto Show.
