The problem is strictly within the KBB value vs. how much people are willing to pay. If some one is selling their NSX for more than book value and people are still willing to pay for it, yes, it will go for more than $25k. That's how the market works. Earlier NSXs at the moment, is in a seller's market, the later NSX has a buyer's market.
Eventually, the market will have an adjustment simply because you can't have a 2005 selling at the same price as a 1991, and I believe the 2005 eventually will drop down to $30 to $40k range.
I have seen many early NA1 going for less than $25k, in fact, there was one last year sold for $17k, needed some work, but not $8k worth of work.
Vance comon........ a 2005 will never be $30k.
You can bearly pick up a nice 93 Supra for 30k
Does no one realize a same year early 90's Ferarri 355 and NSX with same miles are worth roughly the same even though prices new were nearly double?
That being said our cars aging like Ferrari's with even less production
7200 Testarossa's
11,000 355's
8,200 348's
Even Delorians are now over $50k
The only thing keeping NSX's from ridiculous value is the fact that 5-6 year old ones still exist. If Honda would have made 8000 NSX's and stopped production in 1995 by now a NSX would be more today than its $60k new at the time. It's collectors economics. The only thing affecting old NSX values is that "Newer" one are still available......
once all of them are over 10 years old (ex 2015) it wont matter if you have a 97 or 91 and they will all be roughly the same price, probably over the $80k New price. By 2020 it wont matter if you have a 91 or 05 they be worth double what they were new.
It took the supra 10 years after stop of production (1996) to start climbing which was 2006. Now their worth more than new.
There also about 7000 Panteras built in total which although awesome collectibles are way inferior to NSX in build quality and historical significance they were NEW about $10k in 1974, used in 80's for $4-5k Now 30 years later try picking one up for under $40k. And economically $10k in 1974 equals around $30k thats still over inflation.
88-92 911 Turbos were $40k new try finding one for under $40k even considering ridiculous production numbers over 70,000 911's produced with the 3.2L from 84-89. not sure how many of them turbos, gotta be at least 10,000.
The NSX in 2020 will probably be the same price as a Testarossa as time will tell.
I could write a book about future Desirability & Value based on Rarity and Social Value plus future inflation. It can all be predicted and anyone who doesn't believe that is missing out on some real opportunities.
Rule for cars is.....
Everyone wants at 40 what they couldn't have at 20.
Who ever figures out first, what and when that applies to, makes allot of money.
If I didn't have other means of making money I'd be collecting NSX's, & BMW 850's the only flagships of the 90's that are still cheap really really cheap. Also just wait until 2020 comes around and the 1990's video game generation is paying a couple hundred dollars for nostalgic super Nintendo's consoles that can be bought right now for $20. $10k worth right now could mean $150k in 12 years. better than the stock market.
