I just made a post on the Dealerships forum, because I suspect that Audi dealers collude with each other. Rather than repeat myself here, I'll link to that thread.

Your feedback and experience would be greatly appreciated. Thanks.

 

Update: I no longer think Audi dealers collude. I've been in negotiations with several Colorado-area dealers. I just had to pester them multiple ways in order to get some of them to respond. Maybe part of the problem is also that the original email I sent out might have been filtered out as spam.
