that's reasonable, but I have seen as much as 10K taken off an 08.
Why can't you live with an 08'?
The differences between them are very small, minus the PCM3.0/bluetooth/live XMtraffic.

All those can be swapped out in your 08' if the price of the 08' justifies it.

You might still be in the green if you go that route.

 

stevens creek has like 4 GTS w/ atleast 10k off. some hard times these days..
