I really do mean this as an attempt to help you sell it: if you could have the mirrors, cowl vent and all the trim painted black like it should be and you can find some LX tail lights, you might be in business for around the $5k mark. There are a lot of good things about your car, but a mustang enthusiast willing to pay $5k for a '90 will not be willing to have to go through and repaint all that stuff. The red interior and automatic aren't typically the first options of choice, so taking care of the things I mentioned may help you sell it quicker. Very clean car though, best of luck on your move!
I changed the LX tail lights out as a personal preference; if it is a deal breaker for someone I can sell it with LX tails. It was kind of a personal joke; you see GTs all the time with LX tails.
I'd rather the trim was painted the correct colors but the decision was made before I owned it. Again if this is a deal breaker I can get all the trim for the car in black if the buyer prefers.
Red interior and automatic are a personal preference kind of thing. I am fine with them and I'm not striving to please anyone else with my own car. Likewise the price I ask is up to me.
I love the car and if it's nobody's cup of tea I can always put it in storage. I know how rare cars like this are going to become and how much blood and sweat I have put into this one. I believe my asking price is a fair starting point and it can be flexible if someone has a reasonable trade or cash.
Otherwise I will say thanks for the free bump and good luck finding the car you want.
