The gods of automotive design say that five years is too old for a car, so Ford went and redesigned the perfectly good Mustang for the 2010 model year. Fortunately, Ford didn't fix what wasn't broken, instead choosing to enhance design elements of the Mustang that make it such a good take on the classic 'stangs from the late '60s and early '70s. For this update, the hood gets bulgier, the front fenders drop a bit while the rear fenders climb a little higher. Roof options include metal, convertible soft top, and glass--the latter a unique design from a company willing to take chances. Ford has some of the best cabin tech going, with its Sync system, an option finally extended to the Mustang, along with a kickin' Shaker stereo.
