There are a lot of good body shops out there that will be able to match the paint these days, so I doubt you would need the entire car resprayed ( be careful, my car went in for a respray and I got carried away........ see my build thread).
There is no harm in getting a few quotes.
On the other hand, I know what it is like to drive an NSX that doesn't quite look its best, and even back then , it still had a lot of admirers. Cosmetics are nice, but mechanicals and electrical are far more important .
