CupCake:
The '97 GT looks like a good deal.
I read the CarFax report and it gave that Mustang a clean bill of health and showed only 3 owners. Odometer mileage is excellent for an 8-year-old car and it doesn't seem to have been in any accidents. The price is also fair for the vehicle. The rest is up to you, as only you will see the 'Stang close up as well as drive it. From here, I would recommend it, assuming the paint and interior are good and the engine runs well.
I wish you the very best of luck with it, CupCake.
