Maserati is a lesser-known Italian manufacturer of ultraluxury cars that disappeared from the U.S. market in 1995 and returned in 2002 under new ownership. Once owned by Ferrari, Maserati now shares parent company Fiat with Ferrari and Alfa Romeo. Maserati puts more emphasis on luxury, and Ferrari on sport. Both brands are styled by Italy's Pininfarina design studio.Maserati's two current models are the Quattroporte and the GranTurismo. The Quattroporte is a full-size sedan with seating for five. The two-door GranTurismo comes in coupe and convertible versions and has four seats. Both V-8-powered models come in "S" versions that add power and sportier suspensions. The Quattroporte Sport GT S adds even more power and other upgrades.Maserati is headquartered in Modena, Italy.
