It's an SG/Black M3
.
I don't know if there is a service bulletin on the software update; on the invoice it says 'complaint correction' not service bulletin if that means anything. I reported the complaint that my car had increased emissions warning message.
I got a winter package for it but I still have my other car so I really don't use it much in the winter. Just on some dry days to keep it running smoothly, once or twice a week so far. 19" Blizzak 225 on front, 265 on rear for winter.. Was on sale for $850 USD incl. shipping on Tirerack
