"If you look at the economy right now, there may be some uncertainty to make people wait a little," Christian Mastro, Lamborghini's Asia Pacific general manager, said in an interview on Friday.

"The number of people able to spend this kind of money is limited, it's not unlimited."

The comments come as growth in the world's second-largest economy cooled to the slowest pace in more than two years in the fourth quarter and the trade ministry described the export outlook as "grim" last week.

Lamborghini's sales jumped about 70 percent in the country last year as rising incomes pushed up the number of Chinese millionaires and stoked demand for luxury goods. The sportscar maker sold a total of 342 units in China last year, up from 206 units in 2010, overtaking the U.S. as its largest market.

Lamborghini joins Rolls-Royce in forecasting more muted demand for ultra-luxury cars in China, which has grown to become the largest market for automakers from Audi to General Motors.
