My dealer emailed -- my 530xi is in!!
Just got the word an hour ago! They say I can pick it up any time Thursday or after. Yeah!!!!
I'd like to get it Thursday, but won't be able to get there till around 5 or so. I'll probably wait till Friday morning because I don't want to go late Thursday and have all of them in a hurry to get done and leave. Plus, if I wait till Friday, I'll have a good part of the day to tool around for a bit.
