The price-range is for an independent shop (low-end) to an Acura dealer service-center (high-end) w/ a NSX-certified tech' and discounted/price-matched OEM parts.
(though, I'm not entirely sure if it includes valves-adjustment, as often it's stated to be 'case-by-case'; however it does include everything else)
Well, that's one possible reason for the discrepancy.
I've checked around (today) and for a complete 60K service (valve adjustment, fluids, filters, plugs), the independent shops are charging $800-1100 (low end is a guy working out of his home garage, high end is a regular independent mechanic with a shop and employees) and the dealers are charging $1000-1300.
It's not about dreaming man. I'd love to trump up NSX values all-day long, I'm such a NSX fan-boy to begin w/.
I don't "trump up NSX values" and I resent the snide insinuation. I really don't care what they sell for, as I am not in the market to sell or buy. I am merely an observer, and am well aware of what cars generally buy and sell for. And the simple fact is, you just can't go out and buy a car at the prices you indicate. Every time anyone has posted a particular car with an unusually low asking price, such as you are doing here, I've looked into it for further details, and 9-10 times out of 10, the car has some undisclosed problems and/or is not fairly represented in its listing. You can read "excellent condition" and find that the finish and interior are truly beat up, "full service and maintenance history" and find that the timing belt hasn't been changed since the car was new, etc. The sad fact is, this board is frock with tales of someone hopping on an airplane thinking they were going to get a bargain, only to be severely disappointed once they actually saw the car in person. Sure, there are immaculately-kept cars that don't have such flaws, but usually the owners of such cars ask, and get, a premium, and such cars sell within days, and are rarely advertised on Autotrader or similar websites.
Also, the few active sales/dealers/flippers on 'Prime that I speak to regularly have affirmed my figures.
I am constantly talking to people who are buying and selling NSXs, people who have been doing so for months, trying to see what they can get and where the market is. And the numbers above are simply not representative of the market; you cannot go out and get a '91 NSX with average miles and decent condition for $22,500 as you claim (or even $25,000). Which is why there's a recent topic on NSXprime called
The Mythical $25K NSX.
Again, I'm not saying that this
never happens. As you mention, it's possible you may be the lucky guy who just happens to talk to the guy who wants to dump it on the one day he makes that decision. But it's just not common, and you can search for months without ever finding cars at the prices you state.
There is a difference between ideal perception and perceivable reality. Ideally, the various models should conform to the NSX Prime pricing-table or relatively close to it. Reality is that a clean-titled, average-mileage, and maintained/serviced NSX can be had for a very surprising price.
I don't see the NSXprime pricing table (in the FAQ/Wiki) as "ideal" in any way. The market for used NSXs can move up and down as it pleases. As it happens, in my most recent experience and observations, the values in the pricing table tend to be quite accurate for the '91-94 Coupes that comprise the majority of NSXs, but overstated for the newer cars, and particularly so for the '02-05.
so I guess if I were looking to sell my 92 w/73k and maintenance records for $28500 that would move pretty quick.
If the scheduled maintenance is up to date (and won't need a timing belt in the next six months), there's nothing wrong with it (everything works properly), there are no undesirable or major modifications, and the snap ring issue has been fixed, then you should be able to get $30K if it's in reasonably good condition, and $32-33K if it's truly immaculate (glossy like-new finish, no visible wear on the seat leather, etc).
