The only thing I think about one of the new car ads is the one where the woman gets a used BMW and complains that her son "took a 29,000 mile joy ride." They make her look dumb enough to think that her car was a new car. I might write an email. The last time I did this, I wrote to Toyota because they had an ad that said something about a father enjoying seeing his son graduate from college and his daughter get married! I think it worked, because the ad disappeared shortly after I sent the email.
Or, I could go down to my BMW dealer and tell them I refuse to buy another one because I am too dumb to know the difference between new and used...
But I won't do it today, because my car is there for service.
