Setting out to prove that what's small in size can be big on style, the popular Fiat 500 has undergone a makeover, courtesy of its Italian compatriot, Diesel. The new Fiat 500 by Diesel sports interiors inspired by the label's iconic denim: black interiors are stitched with yellow thread, and the front seats have a special "fifth pocket" on the side. Limited to 10,000 cars, it's exclusive to Europe and Japan.
