Nice shot, Dénes, thanks for sharing it with us! Here are two more images of the same plane. Not very good ones, but I think they offer some insight.
At first I thought this Ju 87 might have been one that transferred from German to Hungarian use (with the Balkenkreuze properly adapted), but perhaps it was just some written-off example on which someone tried his painting skills. The swastika is missing, a common sight on decomissioned Luftwaffe planes and there seems to be a crudely painted "1" just in front of the fuselage Balkenkreuz. This fits neither the common Hungarian nor the German marking style.
But this is just speculation on my part. If someone has more and/or better photos of this bird, I would also be happy to see them
Cheers,
Christian
