70 340 Swinger-What's she worth?

OK guys I need some guidance here. I found this 340 Swinger for sale. It was painted 8 years ago and at that time received new quarters and fiberglass fenders. It is no.s matching with 81,000 original miles. Original interior and has not been driven in years but runs well. I am too far out of the loop to put an honest value on it. Any help out there?
