Have you driven it? If you're asking "anyone have experience with classic cars" I suspect that you don't know mustangs too well. The reason you invite such a beast into your life is because you love it and want to take care of it. You want to wax it, you want to change the oil, etc. The mechanicals on a '69 mustang are primitive and straightforward but the paint, coatings, rubber and plastic parts etc are pushing 50 years old. Making it awesome instead of "existent" can be a lot of effort and it's not likely something you want to pay for. Which means it better be something you want to do. Go throw a cruise in it. Then go here and request an Eastwood catalog. Then wrap your head around the care and feeding of vintage iron because it's much more of a lifestyle than buying a Honda off the lot. You may love it... and even if you don't, far better to go into these things with open eyes.
