No hookup on the GM side, but when I picked up my truck 6 months ago I went through Amex and their vehicle purchasing program. Saved over $5K back of sticker and about $2K on all the stupid dealer prep stuff as they told them what they can charge. On the Ford side Brett Durante is at Berge Ford in Mesa, AZ I believe and is moving a bunch of stock lately. Have a fleet guy for Dodge as well out of Utah.
