This is no joke-car, but a serious bus-conversion.

We already have listed this specific vehicle - and it still exists in reality! As a wreck, but anyways. See the links under

No idea, how many were made in total.


P.S. As written in the VW-blog in the link, this bus-wreck was bought in 2009 for 6000 CHF (ca.4000 €) by a well-known dealer for spares for classic VW's, Peter Fried in Southwest Germany http://www.veteranendienst-fried.de/
