When I lived in Alaska my friend’s father owned the Saab dealership. He told me that one day an old guy came in with a very old 2-cycle Saab and claimed that the engine was going out and the car came with a lifetime warrantee on the engine. He thought it was BS but called Sweden anyway. Saab immediately shipped a new engine and paid for the installation. The owner said he had already had it replaced a few times. Now that’s a good warrantee!
