Muscle cars are getting harder and harder to find now a days. If they are advertised in a paper they usually are asking to much or it is totally bagged. To many people watch Barrett Jackson or Car reno shows and think their car is gold. Over the last few years, what I have found is you need to know someone with a muscle car and buy it from them.
Even big block engine are disappearing faster than the salmon are. There are not to many rectangle port BB any where any more so to have a BB in this Nova is an added bonus. BB are a lot of fun to drive but they go though rear tires fasts.
Once it is in better condition apply for collector plates. With collector plate my car insurance when from $840 to $225 and $880 to $250 for the same coverage. I think 1973 is in the collector pate category.
That car has good bones and is a great project car for this winter. I hope to see it at one of the car shows in the future.
Hope you find a local painter and if you don't go to the mainland
