The world's oldest surviving Rolls Royce is to be sold at auction on Monday - and it's likely to go for more than 4-million dollars.

It's the highlight of an auction of vintage cars organized by the Bonhams auction house in London.

The vehicle was built in 1904, just months after Charles Rolls and Frederick Royce began their partnership.

The two-seater 10-horsepower car is being sold by a motoring enthusiast who's owned it for almost thirty years.

Stewart Skilback, a Bonhams motoring specialist, said the sale had attracted interest from around the world.

"It will probably join a major collection, and there's a lot of those in the word, so we expect it to finish up in the hands of a collector, and we think the buzz is simply owning something no-one else can possibly own," Skilback told AP Television on Monday.

Another highlight of the auction is a 1936 Buick commissioned by King Edward VIII.

It's the vehicle that was used to drive him from Buckingham Palace to Downing Street when he abdicated in 1936.
