In case no one else mentioned it, it is believed that the first 62 '91 NSX's and were pre-production prototypes. Some of these have been accounted for in another thread. 000001 used to be in the factory lobby, I think.Ben said:I'm trying to figure this out now, but it's hard, because for 1991, up until #000063, I can't get consistent results. I.E., most cars are not in the system, but a few are. The few that are, they don't have any Carfax records, which leads me to believe that they are all test cars or something so far. Starting with #63, they are consistently in the system, and all have Carfax records.
