Potential car buyers in China have found that an online advert for a luxury sports car was just too good to be true. A Porsche dealership in the the city of Yinchuan listed the brand new vehicle for 124,000 yuan ($18,300, £15,000). That is just a fraction of what it should have been. The Panamera has a starting price of $148,000. The promotion attracted hundreds of would-be buyers who rushed to secure what appeared to be a bargain. A spokesperson for the German car maker told the BBC that the promotion "contained a serious mistake in the listed retail price", which was taken down immediately. The dealership also contacted "every bidder individually and explained the situation with apology". The incorrect information was posted on 30 January and customers who paid the 911 yuan reservation fee have been refunded, Porsche said. Porsche started selling cars in mainland China more than 20 years ago. In recent years the company expanded its footprint in the world's second largest economy as it opened new dealerships. The country is now Porsche's largest single market globally, with sales totalling $6.2bn in the first six months of last year.
