Stevens Creek BMW is my regular go-to dealer for over 3 years with 2 different cars. The service has been fairly good, especially for cars still under warranty. I won't say they are alwasys the best, but at least with reasonable effort for good customer service. Since I don't have too high expectation after reading all bad stories about BMW dealers' service, they have been my choice so far. Work quality is fairly high.
The only two issues are:
1. It's hard to get hold of any service advisors on the phone. If you leave a voicemail, usually get a call back on the same day.
2. Their price is on the high side comparing to other dealers. So if you have to pay out of your own pocket, call around first.
I would recommend them.
