Is this a good price for a 2007 Ford Mustang GT?

I provided the link below, I know this is a GT so it will be priced higher than the v6
But this is a 2007 Ford Mustang GT
-almost 81xxx miles

From mustang's i've seen, I think 17k is relatively expensive.
What would be a good price on this that I could probably talk the dealer down to

You can look it up yourself, Logan.

Kelly blue book or Edmunds web sites will tell you the price you should be paying from a dealer.
