We have a GTS Stagea in Japan on offer to us. I beleive there are a few different models, the one Stuart has is the Autech Stagea - its about as good is it gets, mega money in Japan, talking about near £20K and thats if you are lucky enough to find one.
Our office in Japan had a look for one for me a few months back, they looked thru previous auction sheets for the previous six months and found 2 that had gone thru the Auctions in Tokyo.
I know that Charlesworths near Nottingham have had a few for sale before, not really been interested myself, I'm after two doors less not adding a tailgate . Maybe worth looking at www.charlesworths.co.uk occassionally.
