I have a 98 740 with 94k on it. I have the extended warranty till 100K. Car has always had all the scheduled maintenence, but with the extended warranty almost up I am looking at getting rid of it....Who has experience with a 98 above 100k? I drive all highway miles, so I expect that the car will last.....but I wanted others feedback. Also, what should I expect on trade towards a new 745..My car has the nav, the phone and high miles....
