"You must maintain your Porsche according to the Maintenance Schedule in the Maintenance Booklet and the Car Care Instructions in the Owner's Manual and keep the receipts as proof of maintenance"

Thanks bmuss. I'm just worried that somewhere there in the fine print there isn't something like: "All service has to be performed by a Porsche Certified shop, blah, blah...". If I was the one offering the warranty I'd probably want to have something there that would ensure a certain standard of quality for the work done on the warrantied car.
