Automotive News reports that GM is offering dealers up to $250 in bonus money for every loan they sell to a lender other than GMAC. This latest move follows Monday's report on GMAC tightening lending restrictions, and "is an encouragement for dealerships to seek out other sources of funding," says Mike Mullaney of Hudson Pontiac-Buick-GMC in Poughkeepsie, N.Y. The program pays salespersons $100, sales managers $100 and an "employee of choice" (most likely the finance manager) another $50 for non-GMAC transactions. An end date isn't specified, but the incentive applies to all 2008 and 2009 Chevrolet, Pontiac, Buick, GMC, Cadillac, Saturn and Hummer vehicles. If you buy a new GM vehicle with an outside lender, make sure you negotiate for some of that spiff off your your purchase price. [Automotive News, Sub. Req.]
