I feel really bad for what you have been experiencing. Purchased my silver 2004 for 30k - along with all the goodies.
There is a dealership in Clarksville, TN (see info below). Elivn Overstreet is a good person to deal with. After reading all the posts I went back in my e-mail to find his contact information.
I am not aware of packages, colors etc you are looking for but I called him explained all the difficulties you are experiencing and inquired about a 2004. He was very apologetic for the mistreatment you received from his fellow dealers. He doesn't have a 2004 in stock, however, he has a 2003 (gently used) and indicated that if you contact him, he may be able to locate something for you in the color, options etc through the GM Auctions.
