How come? I'm portuguese and I see old japanese 4x4s all the time, especially in rural places. We even have some Jeeps. 99% of cars here are french, german, or japanese, immersion is not a problem so long as you don't fill the map with Barstows and Grand Marshalls
Definitely true, as seen in this image. Also, Brazil (The other kind of Portuguese) also have foreign cars as well, plentiful of French cars.
Research will help you on the way. OT: If anyone makes a Pico Island map, this should be implemented somehow: winemaker houses like the ones above. By the way, here's the port town I mentioned in my OP...
This could be placed somewhere around the towns, as flagpoles are common throughout countries, including the Azores.
