Do not recommend South Bay BMW.
Perhaps their Techs are above par, their service manager needs to do a quality check on their service advisors. Don't train your advisors to over sell. It makes you look desperate and not trust worthy.
I strongly advise you to pick another dealership.
You'll be dealing with the people up in front 99% of the time post your purchase, not the Technicians who are operating in the back.
