BMW charges 500.00 for front and another 500.00 for rear brakes. I bought brake pads on-line and did it for 170.00 for front and 170.00 for back. This included the brake drum, brakes and sensor.
Had a rear electrical problem with the brake light. BMW wanted 100.00 for computer inspection and 175.00 for the rear electrical bulb holder. I took a small tooth pick and fix the problem.
Battery died. 145.00 at Local Discount Auto Parts store. 185.00 at BMW.
Alternator died. Called the bank to pickup the car.
Overall experience is really nice, but be ready to pocket out serious money for maintenance.
Or do all the brakes and rotors yourself for ~$300..
Or get them all done at an independent shop for half the price.
Not sure why people still go to the dealer.
