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. (Beijing Times)
