Geoff, one needs to see these cars in real life, preferably in a confined display area. When I visited C. F. Mirbach in Bavaria, in the southern part of Germany, there was a separate building - I'll have to find a picture of it. My escort (kkeping an eye on me and my camera) indicated that he was about to let me have a look 'at the holy shrine' - "Mr. Styria, we never show anyone or allow access to this area' - and there, before my very eyes, were two 540K.s, and also I think a couple of Horchs. It was mid blowing to see those utterly huge cars, absolutely resplendent in red and a light blue livery, and looking to all intents and purposes to be totally new cars. I just wish I would have been allowed to take photos. Regards Styria
