Two of the world's most exotic supercars went on show today at a prestigious business event.

A yellow Lamborghini Gallardo and black Spyker C8 Spyder, with a combined value of £340,000, were on display at Dundas Castle, near South Queensferry, outside Edinburgh.

The cars were on show to the 550 guests at the Scottish Business Achievement Awards Trust's (SBAAT) annual celebration of Scottish entrepreneurship.

The Princess Royal was among those at the event, attended by some of the country's leading business figures.

The supercars were present to promote one of the lots available in the charity auction.

Livingston-based firm Rio Prestige donated a package worth over £10,000 to be sold off, which included a weekend's experience in supercar, a stay in a luxury hotel and a year-long membership to an exclusive supercar club.

Founded in 1982, SBAAT has raised over £2.7 million for Scottish charities, as well as recognising achievement and promoting excellence in business.

The 2008 shortlist for the competition included eight individuals competing in three categories - young achievement, international and major achievement.
