That is the Luxon grille replacement made in Korea. It's available from many e-tailers, not sure if any vendors cary it so I won't link to it (sorry).
As for the 380GT, this is the KDM badge for a 3.8L V6. The 2.0T model has a 200GT badge for KDM. These are also available from many e-tailers, also won't link them incase a vendor sells them.
