I am not a mechanic and I have taken my BMW to PALO ALTO BIMMER for approximately 3 years for service. I asked for air conditioning to be fixed, after one month it no longer produced cool air. I asked for the heater to be fixed, after one month it no longer produced hot air. I asked for the automatic door locks to be fixed, before I could be the doors 20 feet away from the car and, now I have to be two feet away or else the doors won't unlock. Needless to say, I paid well over a thousand dollars to have these repairs made and still not fixed. I strongly do not recommended PALO ALTO BIMMER.
Cons: no rental cars available (or at least never offered to me)
