I don't think there's a number distinction for cars assembled in the US, Canada or Mexico. For example all Caravans in the late 90s had 2 prefixes whether assembled in Canada or Mexico. Would be nice to tell by looking.

Earlier this year there was a run on J VIN RX330s before production shifted to Canada (4 VIN). The assumption was only RX400h's would be assembled in Japan. I don't know if that's actually the case.
