MUNICH (Reuters) -Chinese car makers are making inroads in Europe and executives say they are in the region to stay, underscoring a key reversal as brands from BYD to SAIC take market share on a continent where they once struggled to make sales. At this week's IAA Mobility car show in Munich, China's auto firms - facing a tough price war at home - were increasingly bullish about their plans for Europe, dominated still by local brands such as Volkswagen and Renault. "Everything we do starts with the needs of European users," said GAC's president of international operations Wei Haigang as the Chinese automaker showed off the Aion V electric SUV that will start sales in Poland, Portugal and Finland this month, and the Aion UT set to go on sale in Europe next year.
