NSU Ro80 to cross the block at Auctions America

There seems to be no shortage of rarities in the 450-car John Scotti Collection that's currently rolling across the block in Auburn, Ind., at the Auctions America sale.

David Coulthard gives the thumbs up whilst doing doughnuts Sebastian Vettel may be cool, collected and composed behind the wheel of his Red Bull F1, but even an in-control German needs to let off steam when he’s just taken his fourth F1 drivers title in a row. So at last week’s Indian Grand Prix, Seb celebrated his title win by producing a series of doughnuts in his car on the finish line, much to the annoyance of FIA officials who fined him €25k for his celebrations.

It's a V8-powered B-class, complete with AMG-spec 383bhp 5.5-litre V8 mounted up front and driving an old W210 E-class rear axle. Sounds like a promising skunkworks special, derived from an old B200 CDI hack that was kicking about the training centre.
