having availed myself of the 10 year warranty program, I can state that the OPC did not use my 'bought' warranty - it was replaced under the 10 year blanket replacement policy.
this is the exact text (in email ) from Porsche when I queried it with PCGB, and finally got a response.
With regards to your Porsche GT3 and the 10 year warranty, I can confirm that the warranty on internal engine components will last for ten years as from the new vehicle delivery date, or until the total mileage is 194,000 kilometres or 120,000 miles, depending on which comes first.
I appreciate your concern that you were not notified of the warranty. Please be assured that there was no intention to cause you any frustration. Porsche Centre Cambridge are aware of all the required information to claim under the warranty and they will look after you throughout.
The car in the ad looks pretty good value;
only expensive bits missing are the axle lift & PCCB, but neither are on everyones wish list.
The recall campaign was to replace the 'engine bursting into flames' option
only just up the road from me... might take a drive out tomorrow for a look see
