Awesome find! I've seen this one more than 10 years ago in The Netherlands.
So it has been exported to Poland. And the guy is now driving around with a frauduleus Dutch license plate. Makes it even a more interesting find.
So it's a very popular car, but it's not in Poland, he was just passing through :)
Even though he is just passing trough, the car has been exported from The Netherlands, which makes the license plate false. It has not been registered since 2017...
