Porting cars from Asseto Corsa

HI everyone
so my question is,is it hard to port car mods from AC to Beamng Drive?
there's a lot of cars (mods) on there that would be so cool to have them here,like those classic Alfa's or any classics for that matter.
pocket rockets from Europe of the 80's and 90's....
all I see here is Mercedez and BMW like I'm the Baltics or something...

Thanks a lot and keep up the good work bringing us cool cars and maps
