Call 1 800 PORSCHE for customer service to find out when the warranty was started. If you are the original owner and your car was sold to you as new, then the selling dealer will have some explaining to do. Sometimes dealers will title a car to boost their sales numbers for a given period, use it as a demo or loaner. If this is the case, and it was not disclosed to you, then you have a legitimate reason to expect the selling dealer to cover repairs until 04/07.
