This was photographed at Wien Airport on April 27th, 2010.
I have not been able to find any photos of it on the Internet and the buses with close numbers plates are not Setras.
I saw a Postbus Setra that looked close to my photo and it was described as a S313UL.
Is BD13180 a S313UL or something else. Setra 313 i have 13 rows of seats but from the outside I cannot tell.
