A number of automobile manufacturers now offer "free" maintenance when you purchase or lease a new car. BMW and Volvo have offered no-cost maintenance for some time, and this year General Motors and Ford also announced free maintenance programs. Just make sure you know what is and is not covered. BMW, for example, will replace brakes and even windshield wiper blades as part of their free maintenance program; Cadillac only covers oil changes, tire rotations, and air filters (in addition to standard warranty coverage, of course).
So when you consider the cost of buying a new car, factor in savings after you make the purchase as well the amount you save could be considerable.
