1988 Ford Mustang GT

I have owned this Mustang GT since 2010 and have pretty good records of repairs and work done. I have not spent much time driving it and probably haven't put more than 500 miles on it during the time I've owned it. The interior is a mess as I think it might have been a race car and someone attempted to steal it in 2012 and the steering column had to be replaced. I replaced the clutch a couple years ago as it takes about a 60+ pound push to engage. I think the engine has been worked because it is very powerful although I have never put it on a horsepower tester.
I had a friend paint it about 10 years ago and he did a great job. It has been garaged in my shop building since the paint job, and I don't think there is much rust on the car.
I'm 76 years old and starting to winnow down my fleet and I have never had a chance to spend much time with this car, so I am going to let it go. I would be glad to answer any questions.
