Disappointed 
2007 BMW 5 Series Wagon 530xi 4dr Wagon AWD (3.0L 6cyl 6M)
Not a good experience
 One of best purchase experiences of many cars over 40 years of driving. Car has its problems, mostly electrical. Especially iDrive is a bad idea. Poor execution. Driver's seat adjusts forward and up on its own. Screen display blanks, iDrive inoperable, no GPS, no radio, no access to system functions or warnings. Reprogrammed multiple times, reverts to same problems in short time. Electronic key replaced 3 times in attempts to cure Comfort Access issue. Nothing.
