What van is this?

Using a handful of internet tools such as Google image lookup, I found this Instagram post where one of the tags says "#uaz452". Comparing the picture in the Instagram post and the video of which you posted the thumbnail, you can tell by the licence plate that they are the same vehicle.

After comparing this picture with google images of a UAZ-452, I think I can safely conclude that what you are looking at here, is a UAZ-452.
