Does this sound right?

I think i might have found me an 04 gt, but i'm not quite sure if the price is high or not. It has 27xxx miles on it and still has factory warranty, and they are asking 15.9k for it. I figured i could talk them down to 15k and payoff on my truck and it'd be a deal and id be happy with a stang. Here's the link. If you guys know of any cheaper that have the black interior please let me know.

around here prices seem to stay higher than everywhere else ive seen. The car is in st.louis and is the cheapest one ove found for the price. There is a dealer over there that is trying to sell an 04gt for 20k but has an 03 cobra there for 25k. so who knows, ill find out next week.
