Thanks for the details on that. I wasn't sure if it was both. My dealer has no issue with the M stock, I actually think they sell many M vehicles they have SA's and Sales that work directly with M buyers and my service tech is always the same two dudes... lol But for some reason they cannot keep tires on the shelf here.
