There are plenty of beautiful NSXs out there. I chuckle when I hear these guys who looked for 6 months or one year for their NSX, especially a 1991 or 1992 model.
There are tons of those cars out there as production was higher than all of the other years. I am in the car business, specifically the used car business. If you want a really clean low low mileage car you might have to step up and pay a little bit more than you wanted to.
I totaled my 95 NSX and found a flawless 96 NSX and had it in my driveway within 2 weeks. Being is the car business, I understand that, almost invariably, a 12 year old car is going to have some type of flaw unless it has hardly ever been driven.
If you want a 95, find potential candidates here on Prime, ebay, Classyauto.com, the Dupont Registry, or Hemmings Motor News- I bought both of mine off of ebay- I did not bid, I called the people- and ask a Prime member(s) to go by and check on the car for you or ask if they know of the car. Prime members will usually oblige you if you are polite when asking for their help.
One thing to remember is that the NSX has a better residual value than almost any production car made( I know there are a few cars that have better residuals, but, they are usually very rare cars of very limited production), and, with a budget of $25-$30k, you limit yourself to cars whose ACV( Actual Cash Value) is $25-$30k.
Most NSX owners know the inherent value of their NSX. They usually paid all the money to buy their car, and, are not usually willing to whore out a cherry NSX for wholesale book. The NSX is one of the rare car's where the blue book value really is not totally reliable.
Dwindling supply due to limited production and wrecks like mine vs an increase in demand actually is creating a very strong market for NSXs of any condition, especially cherry ones.
If you want a wup ass 95, I suggest you increase your budget by about
5-7 grand. Then you can get the car that is a garage queen with low miles and few blemishes. Good Luck!
