I just wanted to give quick update.
I went to Sudbury BMW for my routine oil change and DEF refill.
I was welcomed by the service adviser Colleen. She was extremely nice.
Since I did oil change 4000miles ago, my oil service interval was reset and although my car wasn't showing is due for oil change she agreed to do it. I asked no to get carwash either.
Dealership itself is very nice. They have free breakfast bar with girl that makes your coffee. Nice big screen tv, children room and internet stations that you can use if you don't have your computer with you. Overall very pleased with the service.
