"These changes in pricing and underwriting are related to the current market environment, which has reduced access to funds and increased the cost of funds. The company currently expects these actions to remain in place until the credit markets stabilize and accessibility improves," said GMAC in an official statement.
Notably, last week GMAC also raised by 0.75 percentage points the rate it charges dealers for providing loans to consumers for vehicles that aren't part of any special incentive programs.
