Dollar buying Chryslers

Dollar Thrifty Automotive Group Inc., an operator of rental-car chains, plans to increase purchases of 2007-model vehicles from DaimlerChrysler AG's Chrysler Group by 23%.

Dollar will buy 30,250 more cars and light trucks than the 130,000 already planned, and can negotiate additional purchases, spokesman Todd Dallenbach said Thursday. Dollar will pay $19,000 to $20,000 for each vehicle. The purchase agreement extends Dollar's relationship with Chrysler, its onetime owner.
