Ferj, you have about a year until the next NSXPO which is expected to be held in LV. I wouldn't be surprised to see 100+ NSXs show up. We had 100 show up one early Saturday morning in January at Cars and Coffee in Irvine which is a 3 hour meet! Should be one heck of a caravan from SoCal to LV.
Start looking now as it might take some time (and maybe luck) to find the right one.
