Definitely a car worth restoring as it will get lots of looks and not many left. I like the mist green color and it's pretty rare as far as 1973 colors go.
When I owned my #'s Matching Basin Street Blue 340-4spd Duster with the M52, C73 and V21 codes among it's options it always drew plenty of looks on the street and at cruises. Strange thing was the manual steering, I guess the owner didn't want any hp robbed from the power steering? It's in Syracuse, NY now.
I have records of about 16 Dart Sport 340 sunroof cars and around 12 Duster 340 sunroof cars still alive and ticking.
