Import Data does not always tell everything until you have complete BOL. That was the exact case in case of KIA Sportage when there were over 2 dozen Sportage as CBU but none of it show up on the import Data. The import data accessible to public show, the vessel detail and some other details but sometime refer to BOL and that means the details are there on the list.
We are lucky that we caught the GM6 City imported by Atlas and cleared in January 2020 and that is what Atlas is working on as far as City.
Vendors also sign the NDA and not necessarily they will share everything with public . The test mule is surely a 12TH generation Corolla , developed locally or CBU is something need to be investigated.
