So what that it's almost the price of a GTR? Maybe someone likes the NSX better and this is a rare one. So while there may not be that much demand, there also isn't much supply. And that is what eventually sets the price. Just because someone doesn't pick a GTR over it doesn't mean they have an inability to reason. They just like it better. There are many cars that were "worth more" over the years to many people who looked at performance numbers over the NSX, most every one of those cars is now worth LESS. Vettes, vipers, Porsches, BMW M's, AMG's... even some Ferraris. The GTR will eventually fall into that category as well. There are already GTR's going for less than many late model NSX's. Obviously if someone is buying them, they see something in them that they don't see in other cars even at that $.
People pay $90k for a new GTR because it has a $20k trick transmission, hi tech 4wd system that defies physics, and is able to spank cars costing many more times. THIS makes sense. Some of you, sadly, believe it's worth it to pay $20k more than average for a USED NSX just because it is white. Makes absolutely no sense.
