Mercedes-Benz and BMW (BMW) dealers deepened their discounts on some models in China last month as slowing property and stock markets weighed on premium-car purchases, according to a research firm.

Daimler, Bayerische Motoren Werke AG and Volkswagen AG's Audi are looking to the world's biggest car market to prop up deliveries as European demand sags on concern over the region's sovereign debt crisis. A slowdown in China's property and stock markets will probably undermine discretionary spending, according to Credit Suisse Group AG and BNP Paribas SA.

"Competition is getting fierce, especially in the entry-level luxury car segment," said John Zeng, a Shanghai-based director at researcher LMC Automotive Asia Pacific. "BMW, Mercedes and Audi are expanding their capacity in China and the majority of that capacity is used to make the entry-level models, and that's increasing the competition."

China's vehicle sales have slowed from last year's record 32 percent increase as inflation, higher interest rates and the end of a two-year stimulus plan deter purchases. Deliveries for 2011 may rise the least in 13 years, according to the China Association of Automobile Manufacturers.

Bigger discounts

Mercedes-Benz (DAI)'s 2012 entry-level C200 sedan sold at 292,800 yuan ($46,122) last month, compared with the recommended price of 348,000 yuan, according to China Auto Market, which surveys dealerships in Beijing, Shanghai, Guangzhou, Hangzhou and Chengdu.

"There are phases when you offer customer discounts, like in the phase-out period," Klaus Maier, Mercedes-Benz China chief executive officer, said Nov 21 at the Guangzhou Auto Show. "But currently I feel comfortable."

Dealers offered 6.7 percent off Volkswagen's 2011 Audi A6L last month, versus 1 percent in January at its introduction, the data show. The new version of the sedan will be available in early 2012.

BMW's new BMW 5-series sedan, introduced last month in China, sold at the recommended price of 797,600 yuan, according to the data.

Audi and BMW didn't respond to requests for comment.

Stock market

The benchmark Shanghai Composite Index (SHCOMP) has declined 22 percent this year and is trading at the lowest since March 2009, as a drop in foreign direct investment and gauges showing a contraction in manufacturing add to signs the world's second- largest economy is slowing.

Home prices fell in 33 of 70 cities monitored by the government in October, the worst performance since it expanded property curbs and scrapped the reporting of national average housing data this year.

"For premium consumers, tight liquidity could translate into less speculative opportunities and hence less 'spare cash' for vehicle upgrades," Hung Bin Toh, Hong Kong-based analyst at Credit Suisse wrote in a Dec 5 report.

Premium-vehicle sales growth in China is forecast to slow to 16 percent in 2012, down from the 41 percent pace in the first 10 months of this year, according to LMC Automotive, an industry researcher. China's vehicle sales will probably rise 10 percent next year, according to the auto industry group.

Last month, Audi posted a 69 percent jump in China deliveries to 29,861 units. BMW had a 9.8 percent increase in sales in the country, while Mercedes-Benz increased deliveries by 24 percent.

"Competition is very strong," said Klaus Paur, Shanghai- based managing director at Synovate Motoresearch. "In order to secure your market share, you need to be aggressive."
