2008 BMW 7 Series Sedan 760Li 4dr Sedan (6.0L 12cyl 6A)
Good Car, but much to complexity, both as user and
 Read other reviews, which describe the car as a good handling, very comfortable car, that is overly complex for the driver  and ridiculous in terms of servicing.  All true   I have owned and worked on cars for 40 years, and the unnecessary, and pointless complexity of the controls, particularly of the single knob to control many interior functions is several orders of magnitude worse than any other car, including benz, Rolls, and luxury american cars, mostly GM.   This 760 li  is some techie's wet dream, but a total nightmare for someone who wants just to use the car and have some reliability, and not program it just trying to get some usually simple function to work, like the radio, or AC.   Also, ridiculously expensive service, new key fob and programing at dealers $1000.00 per replacement key  for a $30 to $100 of value.   BMW rips off its customers, over and over.  never buy one again. wife's idea,  very very bad value, but meets her needs for prestige car, all she cares about and I am stuck with the outsized bills, and frequent failures of water pumps, hoses, AC, etc etc etc ad nauseum.  (Must be worse of all cars, and designed to be needing very frequently very very expensive repairs.)  I thought Benz and Rolls were ridiculously expensive and overrated, but this BMW is in a class by itself, almost as expensive as my cessna 441 (about as overpriced as possible, but delivers something special, fast turbo prop aircraft able to get into and out of short fields with max load), and not nearly as user friendly or as well made as the cessna, but with about the same complexity and frequently required very expensive service, like the cessna, without any of the cessna benefits.   Summary, overpriced, piece of ______,  ripoff in every way, but a nice car in the infrequent times it actually runs, and most everything works, between nearly constantly recurring service, to replace something which is overpriced and poorly designed and poorly made, causing frequent failures.    Makes the cessna look like a reasonably priced, and low maintenance machine, which it certainly is not.
