Cute and now even more practical

Ask anyone in the car biz. Cute may get them to buy, but it's practicality that will keep them coming back.

So to keep them coming back to the all-new Fiat 500L and to enhance its "42 percent extra interior space with comfortable seating for five", Chrysler's Mopar brand is prepared to offer owners of its latest Cinquecento variant "more than 100 proven, quality-tested accessories."

"Mopar accessories are made of high-quality materials with seamless fit and function," said Pietro Gorlier, President and CEO of Mopar, Chrysler and Fiat Group's service, parts and customer-care brand. "And they are designed and engineered by the same teams who created this vehicle."
