The most likely explanation is that the original poster got the sequential production number of his VIN mixed up.
JH4NA21642T000412 is not a valid VIN, the check digit doesn't match up.
The correct VIN for 2002 #412 would have a check digit of 8, with the complete valid VIN being JH4NA21682T000412. And, of course, this VIN was never imported to the US through American Honda as a road going vehicle, according to the American Honda database.
It is a US-Spec VIN also, as Canadian VINs have an "8" in the 12th position, and some (if not all) Hong Kong VINs have a "1" in the 12th position. These were the only three markets where Honda sold the NSX badged as an Acura, as signified by the first 3 positions of the VIN, "JH4"
For cars that left the factory badged as Honda in the other international markets, the first 3 digits of the VIN are "JHM". Furthermore, JDM cars have their own VIN structure, but that's not relevant for the purposes of this post.
The most likely explanation is that the original poster actually has US-Spec 2002 #214.
The check digit he gave in the VIN is correct for #214: JH4NA21642T000214
US-Spec 2002 #214 is a Long Beach Blue Pearl/Blue 6-Speed Manual.
Perhaps the original poster can verify if this matches his car. As a further point of identifying information, #214 would have built in the July/August 2002 timeframe.
Furthermore, a look at the Autocheck for #214 shows that it's first registration was January 2003 in Orange County, which would be consistent with the original poster's statements of it being purchased at Cerritos Acura, with the date being well within the margin of when the original poster said it was purchased, and when it would have been actually registered in the DMV system and reported to Autocheck.
And yes, the US-Spec cars were produced with sequential VINs in set production runs.
Glad to see that the S2000 CR info has been completed. I taught someone over at S2Ki how to get the information a few years back, looks like he's followed through and completed the list.
