I thought that too, but the high end market isn't really taking that big of a hit. I'll share an exert from an exotic dealer who gave his insight & follows the exotic auction market even closer than I do.
I will add that this particular dealer also deals in very specific, optioned vehicles & therefore, usually commands high dollar asking prices. For example, his mentioned Diablo 6.0 SE sold for $635,000. He turned down an offer over $800,000 for his SE30 Jota. He has also fielded the sales of multiple LP640s in the $500,000+ range just because they were stick shift cars, moving his last 4 very quickly despite well over Murcielago values. I would acknowledge that Curated is just one dealer selling cars (in a bit of a niche approach), but I have seen it happening in your area of the world as well. I have watched DK Engineering move a TDF LaFerrari, 575 GTC, & 2 PTS Carrera GTs within' 2 weeks as well. It could be argued DK approaches its inventory the same way Curated does, taking specific cars in a different region, but they aren't struggling either.
The only consistent thing I have seen between these 2 & some others is that the vehicles they're selling are very rare-optioned cars. One could believe a lot of these specific cars are coming back on the market because owners need money but the fact they are getting exactly what they're worth in very short time frames, pandemic or not, shows the market for them is still very strong & the cars will remain safe investments given how fast they're coming & going through the market. I think at the time Danoff shared the Zanardi, it was bidding around $90,000 which I felt was a great deal because the last example I saw come up for sale, moved at $155,000. BringaTrailer's Zanardi cleared the listing at $135,000 in the end giving me the conclusion that that particular NSX encompasses the investment potential that those mentioned exotics have.
It appears to me that if the market is slowing down, even with exotics, the rarer examples, whether they're already a Carrera GT (which is softening) or a 1st gen. NSX, will always remain healthy cars to buy into. It certainly can't hurt that 1st gen. NSX values were already slowly creeping upwards under the radar over the last couple years. But just to add a little more insight into the older NSXs slowly being absorbed into a higher tier market (why by my view, the Zanardi would've been a safe investment), there are currently 2 NA1 NSX-Rs & a NA2 Type S Zero coming into market soon. The 2 NA1s are projected $200,000+ & the Zero is projected at would be a record-setting $275,000-$300,00 for a NSX. Of course, until any of the 3 actually sell, I acknowledge them specifically, solidifying my personal views isn't anymore validated than what yours may be.
