I own a 2010 TT, but really wanted a 2008TT. I would still choose the 2010 because it similar in color to my 79 toyota 4x4, so more of a sentimental decision. I like the wheels better on the 2008/9 and 2011 though.
I wish the TT came in white, but sandstorm is close. I just don't like dark colors on vehicles because of they are more difficult to clean and show scratches more. Will the 2011 have the option for a body colored roof and white roof?
I really like the '10 TT in Sandstorm (so much I bought one). After I heard that the '11s were going to be green, I sort of regretted not waiting, but after seeing pics of the '11 AG TT, I am glad I pulled the trigger when I did. It is a cool looking rig, but for some reason I just don't like it enough that I would want one. As someone else pointed out, the green is just a bit much.
I also really like the beadlock style wheels, but they may end up being more trouble than they are worth. Seems like Toyota figured out the same thing.
