Still not sure why so many people are so quick to judge, turned off and disappointed with Ford with the direction away from the "Modern Retro". The new Camaro will be underpinned by the Alpha platform of the Cadillac ATS so the Mustang HAS to evolve and modernize globally. Change is second nature in the auto world. Designers are always tasked with redesigning Aesthetically and Functionally their cars every several years of service.
My source at Ford says that car companies; as a rule of thumb are designing cars 3-5 years out. So what you see on the road was designed and conceptualized 3-5 years prior.
