It’s not worth complaining to BMW since I didn’t buy the car from them. It’s only the brochures. If I did buy a car from there I probably would complain to the board of directors until she gets fired! Just kidding, I won’t do that. I do notice some dealers here see what you wear. If you wear a T shirt and shorts, they will see you like a labourer or something.
I agree with Red Rocket, service will be great if treat the mechanics/service guy as a good friend. I always do that at the Mercedes Workshop and BMW. I treat them like a good friend until one mechanic replaces a new bulb for free without the manager’s knowledge.
