I agree with Maomaonsx. This is a little high. For 45K you can buy a much newer model with a few more miles. My take on this is these cars are VERY reliable and durable. I purchased a 1991 with 17K miles, I paid 38K. I am very happy with the car, it was as close to pristine as you get for a 9 year old car, stored in a heated garage, covered, not even dust in the engine bay. However, since owning it and learning more about the cars, I probably could have spend 4K less for one with 30K-40K miles and I would have gotten just as good a car.
I also agree that low-low milage is not necessarily a good thing. Cars in general need to be used. I will say that the NSX and most Japanese cars, IMO are much more tolerant to low miles usage then others.
HTH,
