1085 is a NOS chassis. It was not built by the factory, in fact it was built many years after the factory cars. It’s been for sale for years. I’d say $3 million at the high end since the ‘Mark IV’ built using the Can Am chassis hasn’t sold with an asking price of $1.8 million.
I was involved in the building up of that chassis. Story has it, it sat in a basement in the US for many years, unbuilt,
parts in boxes. Story panned out when it was delivered to the workshop in Suffolk. Circa 2006/7
