.16 per mile when purchased 4 months prior to end of lease. I'd just drive it and pay the extra. Don't let the lease dicate your driving pattern. If your putting in 400 miles per week i'd rather do it in a 7 than a pos sentra or civic.
edit: it used to be this ^^ on my M5, currently for the 7 it's .25per mile, .20 purchased early.
