Our 2006 750li has been just plain fantastic. The iDrive on the 750li is tremendous if you take the time to learn it and the navigation screen is the best so far. The trunk is huge and the automatic close feature is great when you have you hands full of groceries. I can step into the back seat to put my granddaughter into her seat without throwing out my back. The keyless entry has spoiled me forever. Curves might as well be straight aways. There is no lean-to-the-left, lean-to- the-right when you drive on curvy roads. This car does what you want it to do
You can't have just one favorite feature with this vehicle. BMW had perfected just about everything.
The only thing I would change would be the seats. A little on the stiff side, but that's what the seat massage is for.
