CARS, China's largest used car dealer, said on Thursday that it has raised $818 million in its latest round of financing, as the company aims to expand its businesses in face of mounting competition from local rivals including Renrenche.com.

The firm's single round of financing hit a record high among the country's car retailers, after the company raised around $600 million in October and integrated its used-car and new-car businesses - Guazi and Maodou - last year.

Guazi offers one-stop services for used cars - buying, selling, renting, fixing and insuring - thereby meeting almost any need of customers for such vehicles, while Maodou focuses on the leasing and renting of new cars.

"In the past two years, we have been exploring and innovating business models to suit the Chinese market. We have expanded our services to both online and offline, for both used cars and new cars, and from pre-sales and after-sales to cover the lifecycle of cars," said Yang Haoyong, CEO of CARS.

Yang noted that expanding scales and bolstering businesses will be top priorities, and said the new financing will be mainly used to strengthen Guazi's presence in the offline market and Maodou's scale development.

According to the company, the financing is led by internet giant Tencent Holdings Ltd. Newly added investors include ICBC International Holdings Ltd, Yunfeng Capital and IDG Capital.

Yu Mu, senior analyst from Beijing-based internet consultancy Analysys, said: "CARS, including Guazi and Maodou, placed a large number of advertisements in the past, which as a result helped them raise public recognition."

"With more investments plugging in, the company will have more abundant funds to strengthen advertising and offline expansion to further bolster trade efficiency and users' loyalty."
