Piss away your money at the dealer or figure out how to get transportation (or just Uber) and save yourself potentially hundreds for same quality if not better work at Scott's.
My parents have taken 3 different models of 5's and 7 series back in the 90's and 2000's and I took my 328i there.
Waste money at dealer for their overhead or save/support small biz with good guys. Tough call I know. I"ll go with Scott's and just Uber to where I need to go while they fix my car and save me $ :)
