The Italian brand Fiat left the U.S. market nearly three decades ago, and its return in 2011 through an alliance with Chrysler was somewhat underwhelming—at least partly because there weren’t that many dealerships properly prepared to sell the cars. Today, there are 142 Fiat dealerships in the U.S., and a string of ads featuring Jennifer Lopez, Charlie Sheen, and a steamy scene with an Italian model during the Super Bowl has helped them sell a record-high 3,712 adorable American-market “Cinquecentos” in March, with sales increasing every month since December. Electric Fiat 500s are expected to go on sale early next year.
