not sure about ML, but don't forget to factor in the alignment, which you must do after lowering a car. for other cars, like SL and S which is lowered by changing 4 springs (I used eibach), I paid about about $300 cdn for lowering and alignment.

I also just purchased an ML, and am interested in getting the ML 55 wheels and lowering. How much did you pay for the wheels?

Thanks, and good luck.
