Today I had a service appointment at Irvine BMW at 9am. I reached around 8:50. Waited till 9:15 no one came, finally one gentleman named Gary came and apologized for the delay. I can fully understand the 15 minutes wait as it was a busy saturday. for lot people who are working 5 days a week like me this is the only day where we can service our car.
Early today before leaving for service I received a text from one gentleman named Maz, to check whether I will be having some time to check for new cars, I replied yes, in fact I have started looking for a new car as warranty on my current one was getting expired.
I met this guy after completing my service formalities. He appraised my car and quoted a amount which was below my expectation, I asked him how can a BMW depreciate so much?
Not sure what went wrong - suddenly he switched his profession from a car sales person to my financial advisor. He started telling me that he and his family rides a 2006 Nissan Armada which he brought by paying cash, which was wisest decision he has taken. Well good for him, I ride a car which I want and can afford. Then Maz reminded me that this is not Iran (He said he is from Iran) but United States of America where car's value depreciates.. :)
Then he advises I should buy a Camry !!!! The funniest part was he asked me not to come to dealer for oil change and all as it is costlier...
Irvine BMW, not sure why you put people like this on your customer facing jobs? Anyway it is your mess, I am lucky to have at least 5 different BMW dealers in and around Orange county. You just lost one of your customer.
