Have they got a factory where these mythical buyers can look at one ?
Yes they have, but you will need to make an appointment.
When we had a little "lookey-lookey" a couple of months ago, there were 6 in the workshop at all stages of construction (from bare chassis up to pre-delivery), as well as 2 very interesting looking prototypes of potential future models (a slightly bigger one, and a baby one) None of the ones under construction at that time were for domestic sale, they were all going to UAE & USA.
When we went there for a visit, I was very clear to them that I was only "tyre kicking" and dreaming about what could be in a few years time, but they still spent over an hour & a half explaining in detail every facet of the product. Personally, before I'd seen one I thought they were way too pricey and out of our reach, until I saw them in the flesh. Expensive....yes, but in my opinion they are a top shelf product, I have not yet seen anything else that matches them (and I've been looking). They do not have a set price, you need to spend some time with them talking about what you want from the finished product, and they will then design and price accordingly. Apparently no 2 are the same, they all start from the same base, but each one is individually built to the buyers needs. They are a serious amount of coin, and the price on it's own would make your eyes pop............but having crawled all over one, I can see where the $$$$ ad up.
If I won lotto I'd have one tomorrow, instead I just have to keep stuffing the pennies under the mattress for another year or so
