Looks nice and ready to use. Can't be too many cars on the road in the Northeast this old with no holes rotted in the sheetmetal.
The market for these unfortunately is small among current owners (e.g. members on this site) and among gas Volvo owners who have heard too many hearsay negative stories about the diesel cars (e.g. turbobricks, swedespeed etc).
Looked at putting it on Bring A Trailer or ebay? May be easier to attract a buyer there. BAT seems to be eager to take no reserve submissions and they can often sell for decent money to good enthusiast homes. This should be attractive as an interesting daily driver for low cost especially as you have already taken care of the big maintenance obstacles like the timing belts, heater core, radiator, etc that usually need attention.
Good luck, no doubt it will make someone happy once you find the right buyer.
