What's it Worth? 1979 Ford Mustang Cobra

So it has been a long time coming and I think it is time to part with this car but I have no idea what to ask for it. Would $7000 be unreasonable?

Thanks for the response. Thought I was shooting a little high. Don't feel like this era Mustang is ever going to reach "classic car" status, but maybe because I do not want to be thought of as "classic". Agree that all original certainly appeals to a certain crowd and usually they are the ones who will spend the money.

Still trying to get rid of this but would like some more opinions. I have not had any serious inquiries or offers. There is a local yard sale going on at the end of the month and hoping to get more exposure, as my Craigslist ads have netted little success. Problem now is the tires look like they need to be replaced and I found a crack in the driver's side window frame, looking at having it welded. Not sure if someone tried to get in it recently as it has been park on the street and one day I noticed the door looked like it had not been closed all the way. When I checked it the strike plate was loose and had moved out, so I just wrote it off as not tightening it enough when I recently replaced the bushing but now starting to wonder. I am looking at $5000 OBO now but wondering if I should replace the tires or just use it as negotiating. Almost thinking I could get more parting it out but not sure if I want the hassle. Thoughts?

Thank you for the input, certainly was going the Resto-mod route. Do not think I would say it is a Pace Car though. Just a 79 Mustang with the Cobra package. It originally had TRX rims but we all know the problem with finding metric tires to fit. Way too costly if you can even get them.
