Gotta disagree here. The NSX is going up because other collectables are going up even more. When you do the research and look around you realize what a bargain the NSX really is, and just how low the production numbers really were, especially the later cars. Expect prices to remain very strong and only go up.
I think "being familiar with the NSX" may actually make it harder to see how other people see the car. With all respect to the Toyota 2000GT (only 337 made, and now trading at close to $1mm) the NSX is the first Japanese supercar. That's makes it a milestone and very iconic car. I really like my silver/silver '03, and if I had the space I'd have a low mileage first year model as well.

I agree that values are going up but, would you pay that kind of money for the car the OP has posted or any one of the recent sales at Barrett Jackson or Mecum? I mean '96 NSX with 12k miles sold at Mecum for $67,000. Plus the Fees to the Auction house?
