German car makers reported buoyant demand, both at home and abroad, last month, the auto industry federation VDA said on Friday. Domestic demand rose, with the number of new car registrations climbing by four percent to 284,172 in September, VDA calculated. And in the first nine months of 2005, new car registrations rose by three percent to 2.499 million. Export orders for new cars grew even more strongly, zooming ahead by 15 percent to 371,100 vehicles in September. That brought nine-month export orders up by two percent to 2.832 million vehicles. A total 528,200 cars rolled off German production lines in September, 10 percent more than in the year-earlier month. Nine-month output was up two percent at four million vehicles, VDA calculated.
