I have owned various high end vehicles and have always found them to be well constructed and a pleasure to drive. That is, until my BMW 750IL. During the warranty period I had to make numerous visits to service for warning lights etc. and the dealer mechanics could never identify a problem. That is, until the car was just outside the 50K miles warranty. Then the problems started en masse. At 52K, major engine repairs (valve seals) and three of the four electric window controls failed. About 1K miles later had to repair ball joints, leaking oils components, battery, etc. My view, stay away from BMW at ANY cost. They claim superior enginerring but exact opposite in my case.
I have leased 7s for 25 years. This is the very best by miles. The X drive showed its value last terrible winter. I haved drived the car for 10 months and hasn't been in for repairs. No bugs. Past 7s have had a number of technical problems and a return for service. This is an exceptional auto and is fun to drive with comfort and safety . The I drive is much improved compared to past models. it is very well worth the cost. Highly recommended.
Got my 750i a year ago. Car was from 4 years lease program. BMW Canada provides extended warranty on it. On delivery there were quite a few problems ( thermostat, knocking in steering column, alignment, weak front drive shaft). BMW fixed everything without questions. After one year of owning have no problems at all.
I have been driving 750iX for 4 months now. The vehicle is solidly built. For those who are interested in purchasing one, following might be of concern; 1. Throttle response on normal mode is below average. I feel it's hesitant to push forward and there is jerky feeling in the process 2. The car gets quite noisy in over 80 mph both from tires and wind. Mine is equipped with all season run flat tires and that could be the reason 3. When I shut off the engine, the radio (or ipod) still continues to be on. I have to press the start button one more time to shut off the radio and this is annoying 4. I have to get really close to the garage door to open or to close
