They are stunning in the flesh - me and @rickyrooo1 saw one, and a Gordon Keeble at the Classic Car Show at the NEC - they also had John Lennon's Iso Grifo which is one mad looking thing.
Yep - some haulier had something like 400 cars and trucks he tucked away - they sold some in late 70's and 80's as he went bust - they are selling the remaining 140 ish cars next month - including a Ferrari California and some rare Mazzer.
I can get two - one is a Porsche T64, and the other is in the same museum I think as my pic, its a VW Rometch Coupe
