I'm getting insurance for my 68 Standard Firebird. Inline 6, numbers matching, strait body with good paint, minor rusting rear quarters and moderate in trunk, 2 speed automatic. Paint is Meridian Turquoise and it is a coupe. I live in Washington State and was wondering what I should insure it for..or what do you think its value is? I've owned this car for 22 years. Im the 3rd owner, the first two are relatives that took good care of it. Again, I'm not selling it, but if I could get a ballpark of what it is worth for insurance reasons, I'd be very grateful.
