Very interesting car. No doubt, the color code on the radiator support is puzzling. I find myself wanting to see 30-40 high resolution photos of lots of key areas.
Personally, I don't see what another poster is seeing with the tunnel under the ash tray. Looks right for the blue paint to me but again more resolution would be better.
If we were playing a no risk game and I had to decide whether it is a 350 mile car based only on the photos provided, I would have to vote that it is a 350 mile car. To me, the zinc and metal under the hood, while dirty, doesn't look like a 100,350 mile car.
I don't think you have showed us the "dent" in the fender but I would try like heck to not disturb the original paint. If it means leaving the dent, fine. If it means finding the best paintless dent person on the planet and fixing without painting then ideal.
No matter what though you have a great car to own and enjoy. No doubt you could flip it...but you could also enjoy it some and flip later.
Welcome to the site! More photos please!
Edit:
One other thing I would do if it were my car...I would remove the original seats and save them and find another set on ebay to restore. If you show the car install the original seats. When you drive some...use the restored seats.
