The spectacle will be a bid to break the Guinness World Record for the Largest Parade of Ferrari Cars -- yes there really is a standing record.
That one was set by Ferrari North Europe in 2007 at the UK's Silverstone Circuit as part of the Ferrari Racing Days event, and saw 385 Ferraris on the track -- later increased to 490 cars.
The latest attempt will take place at Silverstone Circuit in mid-September, again as part of the Ferrari Racing Days 2012 event, and will take advantage of extensions to the Grand Prix track to cram more cars on there.
Ferrari will donate the equivalent of $7.50 to charity for each car that turns up to take part.
