05 GT, $15,800, Deal or No Deal?

I newbie here lookin for opinions on the potential purchase....

Been shopping for awhile, here's the latest seller:

05 Silver/charcoal/auto GT Premium
24800 miles "wife" car been sitting in the garage most of it's life
She is practically flawless

Grab it and run? Or live to shop another day?

Help! Tim

Cmon guys throw your opinion in the hat, I have to make a decision this weekend. This is as far as I could get him down from $16500. Love the car, just don't want to overpay, and I'm a little hesitant because its the 1st year of the redesign...I prefer an 08 or so but they are in the 20s it seems...
