I'm not sure if you're buying your 1st 7 series but trying to buy a 7 series with a 100k + is not the best investment "IMO". Most of us who still have 745's bought them while they still had low miles. If I were you an I had cash to buy one I would use the cash as a down payment on a newer 7 or something else. After a 100k on these cars things tend to break a lot more an leak from everywhere( depending on prior owner). If you really want to enjoy your ride an save on sooner than you think repairs keep looking at maybe 06- 08 750's. The 750's have a newer look with less issues than its predecessor(745). Best Of Luck though.
