Yep, it was advertised on that site last year too, also from Switzerland. Yet another 'look what I've got' advert - if they really wanted to sell it, they'd keep lowering the price until they found a buyer. Seems like it's up for double its true value so won't be selling soon.
I remember a RHD version coming up for sale when I was about to but a G33, think it might have been the only RHD version, not sure. Some guy snapped it up just before me at 12K.
