The NSX is one of the few cars made after 1969 that I think will be a classic.
Values have been going up the last few years.
I wouldn't be surprised in 10 years to see an average first gen NSX going for $100,000
There's no other supercar EVER that can hold 400,000 miles, be daily driven, and still looks good.
The Ford GT is the only thing I can think of that's close, but there's no way it could hold the miles a NSX can.

There are quite a few NSX/FordGT owners on this forum. They (and I) can tell you that there are a few "higher mileage" GT's out there. One is currently over 100,000 miles that I know of. The appreciation on the GT is just crazy, and I tell people that both of my "toy cars" are appreciating. I didn't buy either one with that intent, I bought them to drive, and I do!!!
