Hello, New member here. I am going to get my GN repainted at the Maaco on Gude Drive in Rockville(701 East Gude Dr., Rockville, MD 20850). I had paint work done on my barracuda, they did a great job at a great price. I got an estimate on my GN about a year and a half ago, seemed reasonable at about $2500 for a sand to metal and repaint, no cut ins, body only. They had several old cars in work that looked great. You will want to check it out for yourself, but I'm going with them. My car sounds similar to yours in terms of paint damage.
