I just bought an 08 GT500 Vert this weekend. I called lots from the east coast to the west coast. I found that the lots most willing to deal were the ones with more than 6 on their lot. Guess they don't like carrying the $$$ for sooo many!
I just bought a new untitled 07 Shelby GT for $30k. It has quite a few options including heated seats and satellite radio. It has 1270 miles on it. I'm happy with the deal!
Got mine in Dec 2007. The dealer was advertising them at $5K over MSRP. I noticed they had a slew of Foose, Roush and Saleen. When the salesman quoated $5K over, I laughed, he laughed, and I bought it for $500 over invoice. They appear to subscribe to PT Barnums Axiom. If you are niave enough to pay it, they will charge it!
