The Kuwaiti royal family's special Mercedes could be worth two billion forints.

A rare Mercedes-Benz SLR McLaren Stirling Moss, previously owned by the Kuwaiti royal family, will be auctioned at the end of November. Only 75 units were produced, and this one has only 53 kilometers on the odometer. The 2009 model features no roof or traditional windshield, powered by a supercharged V8 engine with 650 horsepower, reaching a top speed of 354 km/h. It has a unique Fire Opal Red finish and limited road use authorization in the U.S. The auction by RM Sotheby's is set for November 26 to December 3, with estimates exceeding $6 million.
