Most extended warrantee companies are good up to like 10-15 years and less than 150K ... yes ... I recently got a threatening letter saying my warrantee on the Jeep that is in month 2 of a 60 month warrantee is dangerously close to expiring ... and I need to renew it or I won't be covered ... let not your mind be troubled ... you have paperwork from Ford and that is way better than any extended warrantee.
P.S. I moved this to it's own thread in the General Discussion forum at your request ...
