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!
