A Chinese man spent 13 years building himself a car he can take fishing.Wang Hongjun, an electrician from Qian'an city, Hebei province, says his "amphibicar" cost him about £100,000 and 13 years of persistence to develop.After driving it to Beijing to find investors, he told the Beijing Times: "I'm looking for auto producers who are interested in my creation, since I don't want to keep it to myself."Wang says he often drives his creation to the lake in his hometown to fish, and claims he has even taken his son for a 10-mile drive out to sea.The yellow sportscar can be sealed to make it waterproof by remote control. A column-shaped thruster and two propellers are installed in the car's boot.Wang said his car can float and drive in the water, but he refused to divulge exactly how it works."It's a business secret, but I can assure you the car was made entirely by my hands. Each plate was welded by me," he said.
