A Red Bull RB3 Formula One race car driven by Australian Mark Webber during the 2007 season has been listed for sale in the UK for 250,000 pounds ($458,000).

The listing on British website Race Cars Direct was posted late last month by Nigel Baskerville. Baskerville believes that his RB3 is the "only raced Red Bull F1 car in private ownership", but it's not clear how he came to be in possession of the vehicle.

Although we've yet to be able to fully confirm the authenticity of this sale listing, Baskerville does seem to have a little bit of a history with Red Bull's F1 cars: he has, over the past few years, posted a number of times on various sites either asking for available RB3 spares or attempting to purchase RB3 parts from sellers.

According to Baskerville, the car on offer is chassis number two and was driven by Mark Webber in the first five races (Australia, Malaysia, Bahrain, Spain and Monaco) of the 2007 Formula One season.

Webber finished 13th and 10th in the Australian and Malaysian Grands Prix that year. In the Bahrain, Spain and Monaco races, Webber and his RB3 had to retire due to, respectively, gearbox, hydraulics and gearbox failure. The Australian finished 12th overall that season with just 10 points.
