I tend to agree with Doc and Lamont on waiting for the 2011, however, I haven't seen any quotes on pricing for it. One would think that in these economic times a company would not increase the selling price that much, but others have. I personally believe that there will not be the excess numbers of RT's and RTS's for carry over, compared to last years GS's, therefore, fewer dealers willing to cut list prices to make "Deals".
Personally, I traded my '09 GS SM with 9600 trouble free miles for my '10 RTS SE that now has 6800 trouble free miles on it. The only complaint I have is that the rear tire needs to be replaced. The rear tire on my 09 still had close to 50% of tread left when I traded it in.
Just my thoughts.
