Interesting to hear, I didn't know there is an electric vehicle plate in Croatia (there are very few electric cars in Croatia, actually).But this Punto is a TD (I doubt even an electric version exists), so it must be a foreign citizen plate. It only looks lighter because of the low contrast. !;)
I think this is an electric vehicle. It is because I’ve seen something on YouTube regarding electric vehicles in Croatia and found out the plate type for electric vehicles has a lighter shade of green than the one for foreign people and enterprises.
