Nice try .. but I doubt it. According to this source
http://www.autocalculator.org/VIN/WMI.aspx#.VdYwFPlViko the first 3 characters identify the manufacturer and country. 1=US and 9U is Acura so 19U prefix makes sense. Then according to the Wiki (
http://www.nsxprime.com/nsx-faq/nsx-vin-information/) the next 5 characters identify various aspects about the vehicle. For the current gen, it was things like manual vs auto, coupe vs T-type, etc. So, it's any guess as to what NC199 might mean .. 'NC' for New Coupe maybe. But the 199 part kills your idea that 1996 is revelant. Actually, the 9th digit '6' is the check digit .. and for this VIN, '6' is a legit check digit. Then 'G' is the prod'n year and 'Y' is the factory designation followed by 990007 which sort of implies that they won't make any more than 9999 of them. 'G' as the prod'n year doesn't appear to relate to the characters used for the current gen which started at M and ran through to Y (missing O, Q, and U) before turning to 0 to 5 but I did discover a 2015 TLX which has an F in that spot so G for 2016 probably makes sense.
