A full-size replica of the three-wheel "Benz Patent Motorwagen" goes on display at the 16th Qingdao International Auto Show on Sept 6, 2017. The car, made by German engine designer and automobile engineer Karl Benz in 1885, is considered to be the first practical motorcar. A vintage car exhibition is part of this year's Qingdao auto show, which kicked off on Sept 6 and runs for six days, with around a dozen classic vintage cars on display. [Photo/VCG]
