Dollar Thrifty Automotive Group
Dollar Thrifty Automotive Group (formerly NYSE: DTG) is a holding company for Thrifty Car Rental and Dollar Rent A Car, formed in 1990 by Chrysler and spun off in 1997. In November 2012, it was acquired by Hertz Global Holdings in a $2.3 billion deal.
The company at one time also owned Snappy Rent a Car (which was sold in 1994), Eurodollar and General Rent a Car (which was closed in 1993). It is headquartered in Tulsa, Oklahoma.
Prior to 2009, the company primarily rented Chrysler, Dodge, and Jeep vehicles within the United States, though some locations featured other brands, such as Mazda, Nissan, or Toyota. In October 2009, the company stated that it would move away from its traditional reliance on Chrysler Group vehicles, diversifying its fleet to include more brands than before.
DTAG was a Fortune 1000 company and has over 1,475 locations worldwide including more than 835 locations in the United States. In 2006, the company outsourced its IT operations to EDS. As of October 2009, the company had about 7,000 employees, 700 of them in Tulsa.
