Hi, I have a 5 yrs old 316i that is out of warranty. PML offers a $670 package for 3 servicing with engine oil change thrown in. Anyone knows how much non PML workshop would charge for oil change? I'm concern that during routine oil change servicing, PML may detect parts needs changing, etc and charge higher than outside workshop. Hence seeking forum's advice on matter and recommendations for optional workshops to do routine serving other than at PML. Thanks
