I haven't seen very many Chevrolet Exported vehicles,but of the few I have seen,they all had the RPO code ZP-8 listed on their buildsheets.
Officially,ZP-8 was The Manufacturers Statement of Origin code when selling a NEW vehicle from the United States to a Foreign Country,or when transferring said vehicle to an Individual
IN a Foreign Country.It was the Manufacturers designation of making it void of any duty taxes.
