Styling trends come and go, but if there's one thing that has remained relatively unchanged in the past 105 years of personal motoring: the steering wheel.

Although plastics have replaced iron and wood and airbags (1970s) and radio controls (1990s) have been added, the basic design remains the same: a circular ring with spokes connected to a central hub.

The five Lincoln concept models that we told you about on Friday will be joined by the 2003 Mercury Messenger concept at the RM's Sports & Classics of Monterey auction on August 12th.

The two-seater sports coupe prototype of the soon-to-be discontinued Mercury brand broke cover at the North American International Auto Show in Detroit back in 2003. It was supposed to herald a new and more stylish design language for the company while some had also suggested that it may inspire a production model - unfortunately for Mercury, that never happened.

Influenced by the Cougars of the late sixties with a rakish roofline that recalls Ford's GT supercar, the rear-wheel drive Messenger Coupe was designed to be powered by the Dearborn automaker's familiar 4.6 liter V8 engine (the study is not fitted with a powertrain). The folks over at RM Auctions estimate that the Messenger can fetch between US$75,000 and $100,000.
