What's it Worth? 1991 mustang gt

Go over to bringatrailer.com and search Foxbody. Look at what they are selling for. Many many examples to reference. I have mine set to alert me every time a Foxbody is listed. I watch them all. With the limited info, my personal opinion is that's high at this time. I've seen really clean ones go for much less. Again, just my opinion.

Edit... I'd also say you need complete pictures of the engine compartment & every bit of the interior and hatch. Same with exterior. Complete shots of the full car in the picture from every angle.
