How much do you think I could get for this car?

I have a 1997 ford thunderbird. I've had it for two years, the person before me who owned it didnt drive it very much and kept it in the garage for 6 years.

I have not had any problems with it, except that the A/C does not run everytime I turn it on, sometimes it takes about 15-20 minutes before it turns on.

It has 147,000 miles on it, the tires were made in 2000, so that is something that would need to be changed. The inside is still nice. The outside (its a pearl white color) , the rear bumper I hit into a wooden pole, there is no dents, just a green paint from the pole. & The right back turn signal light works, but the cover around it is broken, so I have tape around it.

Based on just this description, how much do you think I could sell it for, given that the person knows of these things that they need to fix?
