If it’s built, that is.

Should the car see production, it will cost a cool €500,000 and just edge out the €460,000 Carrera GT as the most expensive Porsche ever, Automotive News Europe reports, citing “two people with direct knowledge of the plan.”

Officially, the über-cool supercar car we first saw at the Geneva Motor Show is nothing more than a tantalizing concept. But Wolfgang Duerheimer, Porsche’s development chief, said in April that the company would make a decision on producing the car if 1,000 potential customers show an interest in buying one. So how many hand-raisers have stepped forward?
