I was googling some Scania VINs and by pure incident I came across this PDF: http://www.volanbusz.hu/uploadfiles/37_105613-szerzodes-autobusz_berlet-Nyugatbusz-2012.pdf
It seems that those two buses are owned by Nyugatbusz and rented out to Volánbusz. They were both exported from Norway in December 2011. The one on this photo is probably one of those two.
So I would be happy if someone could find out which of the two is the bus on the photo and what may be the registration on the other one?
