Extended engine warranty

Hello together, Can anyone say in detail under what circumstances the extended engine warranty from Saab takes hold, or does not take hold?! As far as I know this factory warranty is extended to 8 years after all. Does this exclude second owner, does it use in principle if checkbook is possible? Specifically, I am concerned about this option with the currently available, well, upcoming engine damage on my 2000er 9-5 Aero. The purchase is only 4 weeks ago, however, the dealer locks itself despite warranty The thing will probably have to be decided before the end of the contract, but until something is decided, the first factory guarantee has finally expired. By the way, please give information about the dealer who would have earned a price for maximum deviation in the behavior before and after the contract. Thanks already for the information about the engine warranty. ck
