A NEW super-posh version of the Mini is to make its world debut next year at the North American Motor Show in Detroit.

BMW describes the Mini Convertible Sidewalk, which has 16-inch wheels, leather seats and steering wheel, as "a car for the true enthusiast who appreciates the fun and exhilaration of open-air driving".

As well as special light-alloy wheels, the Cooper Sidewalk has English leather sport seats and steering wheel. When it hits Mini dealers in the UK from April, prices will range from £16,910 to £20,235.

Andy Hearn, general manager for Mini UK, said: "The Mini One Seven, Cooper Park Lane and Cooper S Checkmate editions of the Mini hatch have been hugely popular, with nearly 8,000 models sold in the UK in just 12 months.

"We are confident that Sidewalk will offer the same exclusivity and maximum value for Convertible customers. Undoubtedly it will reinforce Mini's unique position as a premium small car."

Since its launch in 2004, the Mini Convertible has been a storming sales success and found itself a place deep in the hearts of British drivers.

In 2005, Mini Convertible outsold its nearest competitor by 27 per cent.

The Mini is the UK's best-selling convertible car in 2006, with more than 8,500 models sold this year.

The Detroit show on January 7 also sees the crucial launch of the new Mini Cooper and Cooper S hardtops in the US.

The Cowley workforce is set to celebrate the production of the one millionth Mini early next year.
