This 2013 FIAT 500 Abarth is offered to you for sale by Mercedes Benz of St Louis. When you purchase a vehicle with the CARFAX Buyback Guarantee, you're getting what you paid for. The 2013 FIAT offers compelling fuel-efficiency along with great value. You will no longer feel the need to repeatedly fill up this FIAT 500 Abarth's gas tank, in part because of it's superb EPA rating. This low mileage FIAT 500 has barely been touched. It's the next best thing to buying new. More information about the 2013 FIAT 500: The Fiat 500 is a small 4-seater that, thanks to turbocharging in the new Fiat 500 Turbo and Abarth, as well as a more athletic look, stand as direct rivals to the Mini Cooper S. Like much more expensive Italian cars--and thanks in part to Mopar--the Fiat 500 offers more customization potential than is typical for an inexpensive small car. With a Fiat Studio system at dealerships, buyers can customize with interior and exterior accessories, striping packages and more. Fiat 500 Abarth models also live up to the small but wicked approach that inspired the 1960s-era performance models that inspire it. The idea is to offer high performance in a small car, with a dash of Italian exotic personality and pedigree. Safety is also a strong point for the 500; it's been named an Insurance Institute for Highway Safety (IIHS) Top Safety Pick. This model sets itself apart with strong, track-ready performance (Abarth), practical, stylish interior, Nimble, responsive driving feel, flamboyant exterior, and good gas mileage On-Line Sales Price may not include Mercedes Benz Certified Pre-Owned Warranty *CALL TO VERIFY PRICING AND WARRANTY INFORMATION.
