When they featured this coach on "The Genuine Article," I have to say that I liked it in terms of style. Still, I can't figure out why it costs so much. Probably the leather couches cost in the range of $5000 each, throw in a bit more for the table and chairs. There's nothing particularly fancy about the bedroom (it has a bed). I half recall a nicely configured door that allowed you to open the bath to the bedroom but keep privacy from the rest of the coach. But that's not especially expensive, either. I could see the work involved costing $30-40k tops.
As far as the design goes, it's highly derivative of Christopher Deem's prototype Airstream rennovation. It's very nice, but basically, it's a CCD on a motorhome chassis with a couple of Italian leather couches thrown in.
To a certain extent, I think Ogan may be trying to get a name for himself by being the most expensive. It appears to be getting him press, but I've never heard it mentioned that he's ever actually sold coach to a client. As the old marketing class mantra goes, an item is only worth what someone else is willing to pay for it.
