Great looking M6! I had to make an account just to give you a solid
Out of curiosity, are you sticking with the 5w-40 oil weight in that Minnesota climate? I thought original oil spec was 5w-30 but perhaps the thicker oil helps with rod bearing protection in the summer?
I have been eyeing a M6 coupe in the twin cities, just in my due diligence period of checking into the servicing to make sure I don't buy a problem.
