Well this is interesting The marklin.gr shop is offering these coaches for sale:
http://www.marklin.gr/index.php?route=p ... ct_id=8568 (there appear to be 5 variations)
The construction is not typical and perhaps not for everyone, but I think that this is a creative way to make these unique coaches available. I'm very happy to see this. I'm definitely going to give a couple a try. Mine wont be running behind a Vectron however - the Hellas Sprinter will do just fine.
More detail on the construction method here. Google translate does a pretty accurate job if you don't read Greek.
