There were 89 Gen 2 NSX cars on CarGurus
If you pull out about 10 22s you have about 2.5% of US cars for sale
And then some are modded or salvage titles so 75 cars worth talking about
A good chunk of those are pushing their luck on price , one has about 50k miles so you end up with under 30 cars, so 1% of production (US cars)
LFA, about 174 came to the US, a small bunch crashed or exported so estimate 160 cars here
4 currently for sale which is over 2% of the pool
Personal opinion
Having both driven and ridden in the LFA it is flat out a more special toy
The Gen 2 NSX is probably more confidence inspiring in turns because of the AWD
LFA engine and sound is on a higher level plus the car is highly handmade, mostly out of CF
I think there will be opportunity for price appreciation in the Gen 2 NSX but the timeframe is a total crap shoot
