If it were me and Porsche refused to produce a written list of coverage, I would go straight to the insurance dept in that state.
There is no excuse for this kind of fraud.
BTW-for all of you who have or do buy a CPO car, I would make this a deal breaker. You are paying about $4K for that warranty and it should bloody well be in writing.
If you have already done this dead, at least keep the window sticker and any related advertising about the warranty. You may need it in court.
Man, this topic pisses me off!
