When I purchased this car, it was covered under the extended warranty package. Notwithstanding, the car was in the service bay every two weeks, fixing a sensor, rebooting the computer,checking a warning light. At six years two months and 128,000 KM or post-warranty coverage a new transmission was required; a second transmission tune-up(??) at 133,000 km. The dealerships are at a loss to completely repair some of the noises under the hood: it has become a very expensive guessing game. When there was difficulty starting the car, an alternator and new battery were recommended. An independent garage, they replaced the starter at a third the labor/parts charge. BMW shrugs & smiles and I get poorer!
I loved the high performance drive and the remarkable cornering ability. If you are looking for a road-hugging, highly responsive car with a ton of features that sometimes are difficult to use, then this is the car to own. You have to weigh the ++ with the trade-off of shop time and warning lights.
BMW should have been castigated for allowing the 2002 745 model off the lot. Too many issues with the oversensitivity, too many warning lights. Under warranty the service departments attempt to work with the existing parts; post-warranty, everyone wants to replace the parts. Hmm! It is their worst!
