Your is amongst the most intelligent and well written posts I have seen on this page. I have tried several e-mails to BMW all to no avail. The reply addresses I send to are always returned "Undeliverable." I have even called the Corporate Headquaters with no success. I don't know what goes withe these people sometimes. Your questions are valid, but, they refuse to come out and make a statement. Keep up the good work and perhaps we'll make a breakthrough.
