Couple things...
1. Top is wrong. It should be a 3 piece back window set up not the narrow rectangular slit
2. There is something not right in the wiring.
I Agree that in the current market for these cars a Condition 1 would not be an easy sell in the upper 40's/lower 50's. What was paid I would figure is limit. This is of course, a personal opinion.
Remember if any old car, regardless of make is NOT as represented (all original, restored to factory specs, etc) you can take legal action against the seller. This is a matter of record regarding various court cases in various states along these lines.
