I think we're kind of missing the point here.
Beauty, as always, is in the eye of the beholder (as they say) but in this case, beyond aesthetics, another opportunity has arisen. That is the opportunity to own something not just rare, but (and I don't mean to offend owners of the more successful/popular "volume" models here) in fact unique; like no other.
And that is something I can really see the appeal of.
This actual car will exist in pictures from it's production era and will have been the subject of specific and prolonged deliberation and will have provided (fleetingly, I imagine) transport for some very serious figures from the company's history. Provenance is everything in something of this age.
Beyond aesthetics, as I think it's quite a shock to the modern eye, this thing is literally the missing-link, from the past, in the current model line up. But then you all know that...
Sorry, I'm just trying to say that I think it's the rarity that commands the value...
