It is best if the NSX is kept a legend at this point. Even if a redesigned model did come into production, it's just not going to have the same impact it once had during its 1989-1990 debut which was surprising enough indeed to the sportscar market. As Shigeru Uehara had mentioned, "-the supercar boom is over -but there will always be those who desire something special." I do believe that Acura will advance with a new successor intended to compete with the likes of GT-R and LF-A, but it's no NSX nor will it be better than the NSX. I'm sure that many agree here on this forum that the NSX is a timeless design so how certain are we that a new model will look twice as better? In terms of refreshed design, it just seems LIMITED because we often say "hey it looks like this or that car!" so the Acura designers really have to come up with something that does not borrow any styling cues from other cars.
