Called another dealer and asked...same run-around: nobody uses those, bmw doesn't want people to use them, they don't make much difference, it's a waste of your money. WTF?
I'm not a math expert, BUT if 7 MSDS will drop an MF 0.00049 and you can see a $700-900 savings for 3 grand down over two years, that seems like a big difference and a great ROI.
Weirdest thing, I heard about MSDs from a Beverly Hills dealership in 03. That guy got my email about a possible 330i purchase and turned me on to MSDs and leasing. Ever since all other dealers/salesguys get ansty when I mention them.
