No, the NSX isn't a stepping stone type of car, Oyagi. You may have a personal preference for other cars, and you may want to have a Ferrari in the garage for weekend fun while driving an NSX day to day. Or an NSX in the garage and a sports UTE for daily blizzard driving. Or you may change around from Carreras to NSX and sometimes back, but you don't step up from the NSX unless you're moving into the half-million-dollar market. You just step sideways as your taste dictates. On the ladder of sports cars, the NSX is still very close to the top, even five years after they stopped making it.
Great post, but if you look at my original post you'll see I'm very much in the NSX camp. I just wanted to see what others consider the NSX to be in their automotive life.
I've got too much sunk into my nsx, too much time devoted to let this baby go. It is my handmade car, custom in almost every way possible. It might become more track focused in the future depending on what my tastes develop into in the coming years but I think my car's reached its end with me.
