2011 As an accessory, Fiat offers buyers of the 500 a built-in perfume diffuser for this retro-styled little hatchback. Available in white or black, the electric diffuser fits between the front seats. There are currently three fragrances: Citrus, Essence of Night and Breath of Fresh Air. The intensity of the scent can be adjusted by pushing the plus or minus buttons located on top of the device. About the only drawback—other than the giggling of your friends—is that the diffuser effectively turns the dual front-cupholder into a single drink unit.
