New car two years warranty on my 997 is expiring in March and the local OPC has offered me a one year extension for the equivalent of GBP 2,300. It also includes the "Comprehensive Maintenance" (covering "all consumables"- except tyres) and two free checks per year. The previous Porsches I owned were all second hand well past warranty period so this is a first for me. Has anyone extended the warranty ? Is it worth it or once you have a problem they will come up with lots of hidden "exceptions" and "extras" ?
