Since we got finally got an European region tag, Tatra - being from Central Europe - certainly is the one that should have it.

Burlak given that it is included in the same DLC as the European region and that it has the European plates, it too should get ability to be easily bought in Scandinavia region.

The vehicles listed below:
tatra_805.xml
tatra_t813.xml
tatra_force_t815_7.xml
tatra_phoenix.xml
burlak_6x6.xml
should have the tag Country="RU,CAS,NE" inside <GameData />

Frankly it seems like Eurasian vehicles (Russia and the band) should have priority in the truck store over American vehicles, and at best, it's the Neo Falcon, Royal and Land Rover that should get an exclusive inclusion, alternative you could have the whole region set exclusive to European trucks + Falcon and Burlak or make all the trucks included in this region (tho the American ones really don't fit).
