Just did a quick look at G8Board.com and one dealer (Nino) has a 2009 Base GT (No Premium and no sports) for $27k and I don't know what Miami sales tax is. When I was looking at G8's they had additional rebates for vehicles that had been sitting on the lot for a certain number of days. With 2,000 miles I would think they would be willing to deal since it is pretty much a used car.

When I was looking at G8's it seemed like G8Board.com had the most dealer activity.
