That is a cool car! A really cool car! And with great options.
I don’t think painting it would add much value even though it’s not really all original with the grill lights and side marker lights added. It is usually best to spend as little as possible on these early A-bodies.
If you’re looking to resell it a quick mediocre quality paint is a big turn off for me and may actually hurt the value. To do a nice high quality finish would cost more than the car will ever be worth.
I think I’d consider adding AC if I was going to drive it. That would make the car much more usable to anyone interested.
If it was me I’d spend some time enjoying this car and then decide if I want to keep it long term and then it makes sense to spend some money on it.
I’m in a similar position with an Opel Manta. I bought one that has zero rust & mechanically is great. But it has a poor repaint and the wrong seats. It’ll never be worth what it’ll cost to make it better so I just drive it
