The plan was to gather 911 Porsche 911 sports cars in one place.
But numbers swelled at the weekend to an amazing 1208 examples of the Stuttgart icon at the Silverstone Grand Prix circuit in Britain - a world record number for a single gathering of 911s.
The spectacle, which raised funds for the Hope for Tomorrow cancer charity, was led by a number of famous Porsche personalities as thousands of fans looked on.
Mark Porsche, son of 911 designer, Ferdinand Alexander ''Butzi'' Porsche, and great-grandson of the marque's original founder, Ferdinand Porsche, was joined by a number of the sports car manufacturer's most successful racing drivers.
Former F1 driver and five-time Le Mans winner Derek Bell, along with Richard Attwood – winner of the 1970 Le Mans 24 Hours for Porsche – and fellow ''legend'' and race driver John Fitzpatrick were also there.
Porsche owners and enthusiasts made up the remainder of the colourful convoy culminating in the remarkable world record number, which spanned virtually every possible derivative of 911.
Among the parade were the most famous 911 models from past and present, including legendary Carrera, RS, RSR, GT, Speedster, Targa and Turbo variants. A number of distinctive race and rally versions of the 911 also featured in the cavalcade.
"Of course, the 911 means a great deal to me as it's my father's big design and it will always have a special place in my heart," Mark Porsche said.
