No other automaker of repute sends their flagships for overseas production. You can always bet the Lexus LS and the Landcruiser nameplates will be made in Japan.
BMW makes the M3 and M5 in Germany. VW makes the Golf R in Germany even if GTIs are made elsewhere. Mercedes makes the S class in Germany, while the C class is made here. Nissan makes the GTR in Japan. Porsche makes the 911 in Germany while the Boxster/Cayman are made in other factories (one generation in Finland).
