I was looking to purchase Haval H6 HEV and one concern remains with me is about their aftersales service. Can users guide me and tell me how is their experience regarding H6 HEV and Dealership's service. I have heard very great things about Changan's aftersale services either their warranty and everything given. Moreover please guide me regarding choosing between Oshan x7 (Future sense) & Haval H6 HEV.
