A valet parking attendant managed to plough a 200mph supercar through the front of a shop after mistaking the brake for the throttle in a Ferrari 599 GTO worth £300,000. The Dutch owner of the 2012 supercar was waiting in the Hotel Exedra after attending a meeting of the Ferrari Owner's Club with his wife in Anzio, south of Rome. The car's owner entrusted the car, which is one of the most powerful ever produced by Ferrari, to a parking attendant who attempted to return it to the hotel in a timely manner.

The £300,000 supercar can hit 60mph in just 3.3 seconds and ploughed through the shop front . However, instead of pressing the brake when approaching a shop front, the driver mashed the throttle, unleashing 671bhp from the magnificent 6.0-litre V12 engine, which ordinarily could propel the car to 60 miles per hour in less than 3.5 seconds. The Corriere della Sera said that the driver, Roberto Cinti, 38, told police following the accident: 'I got confused. Instead of the brake, I pressed down on the accelerator.' He blamed the car's semi-automatic transmission for bamboozling him. The identity of the car's owner is not known, although insurance investigators are believed to be looking into the cause of the crash. Only three Ferraris have been designated GTO and only 599 of the latest model were produced. Such is the exclusivity of the 599 GTO, that owners could not simply arrive at their local Ferrari dealership seeking to purchase the model. Instead, they had to be invited by the Italian company to hand over their cash. Only 599 of the Ferrari 599 GTO model were built, which is the manufacturer's fastest ever road car .
