Go to the G20 forums, which can be found here:
https://g20.bimmerpost.com/forums/
More specifically, you should post in either the Southeast regional forums here:
https://g20.bimmerpost.com/forums/fo...play.php?f=758 ....
....or just in the ordering section here:
https://g20.bimmerpost.com/forums/fo...play.php?f=723
I'm sure someone in either of those sub-forums will be able to direct you to a reputable dealership in your area.
