Here's a bit more of the story from a guy on bmwcarmagazine forum who says he knows the seller:
"I can't find my original post which included pics of these cars, thought you might Simon.
Originally owned by my mate in Hopton.
I've known him for almost 30 years and remember when he bought them.
I lived away from home above those cars for 18 months and oh how I wanted one of the BM's.
I looked after his boys racing for him, when he was out of the country.
He well maybe a billionaire but he's a quite private non domicile Monaco resident.
I emailed him from Rockingham yesterday to let him know his cars were all over the internet and he was being quoted as being a billionaire, he always tells me he's skint.
I can tell you he certainly hadn't forgot about them because the race workshop is in the garage next door.
I'll see him next week at Snetterton for an update.
It might interest you to know when I originally posted pics of those cars nobody asked if they were for sale.
Back then he wouldn't have sold them anyway but with a big investment in his lift truck factory in Taiwan and 2 boys who want to continue racing circumstances change.
His oldest boy has been testing GP3 and that is a highly expensive series to compete in.
I still can't get my mind around the fact he has sold them.
The RS200 doesn't run and the register never knew where the car was located or who owned it".
