What do you expect? The japaneese manufacturers have always been the great rip off artitsts of industrial engineering.
In the 70s datsun's 240z was a rip off of a 60s ferraris and jaguars and toyota's 70s celica (I personally owned a 75) was a rip off of the 60s camaros and mustangs.
While the japaneese are finally starting to do their own thing with car styling the NSX does appear to be one of the old 'rip off' hold overs.
