Maserati North America’s 1.9 percent financing offer for 60 months on its flagship Quattrosporte sports sedan provided a sneak peak of the automaker’s new captive financing arm, which is expected to debut at the Detroit Auto Show, according to a report in Automotive News.

The new financing arm is a subsidiary of Fiat S.P.A.’s CNH Capital America LLC financial service company, which is located in Lake Forest, Ill., and has provided financing for Fiat’s New Holland construction and agriculture equipment units in the United States. The finance arm is also likely to provide financing for Alfa Romeo when it returns to the United States in 2009.

Maserati officials were quoted in the article as saying the financing offer for its Quattrosporte, which starts at $108,750 (including shipping and gas guzzler tax), is a one-time deal expiring this Sunday, Dec. 31. The promotion, which also offers the option of 2.9 percent financing over 72 months, is serving as a test for the exotic brand’s new financing arm.
