^^ eh… not quite!
the above only applies to vehicles imported through the RIV, i.e., vehicles from the USA that are newer than 15 years old
vehicles that are 15 years old and older do not go through the RIV and are not subject to any compliance requirements
the import process for a 1989 240SX from the US is the same as it would be for a 1989 180SX coming from Japan
