We love that automakers are bringing back interesting colors. Just look at BMW's stand at the Detroit Auto Show. Silver, black and white are so ubiquitous that it's often difficult to find anything that really shines. Aside from just aesthetics, there are cost reasons to opt for a more interesting shade of paint. Yellow, orange and green cars hold their values better than any other paint out there. A Need for Green Mustang is potentially worth more than a red or black one.
Ford hasn't said if Need for Green will cost extra. It will be available on Mustangs sometime this summer.
