This car is seriously quick, and handles like it reads your mind, no second guessing. Makes you feel proud to be driving a wagon.
However:
When the sunroof is open it causes what feels like unbearable ear thrumming from cabin pressure. The only cure is to crack a rear window or close the sunroof part way. BMW service manager states that other wagon model owners have reported the same problem, and there is no fix.
If you have a color choice, think hard about tan as it is very difficult to keep clean, but worse, BMW decided to make most of the dash black except for a color coordinating stripe of tan, that runs all along the base of the windshield. My eyes suffer the glare from reflection from that stripe on the windshield day and night. The first time I need a new windshield I am having that tan stripe painted black.
There are many ash trays available, but few compartments to place daily stowage such as sunglasses, cell phone and accessories, etc. To the point that I paid $40. for a rectangular receptacle to replace one of the ash trays in the console rear area.
The rear wagon area cover is most useful. It is very easy to get in and out of it's seat, when loads are really huge and it is in the way. And pulling it over purchases, and releasing it to unload is a snap.
The stowage pockets behind each front seat are so tight it is tough to get anything into them.
Driver seat adjusts everything except lumbar, available only for $2,000 more. After 8,000 miles, I am still playing around with the seat's power adjustments to get it 'just right'. Perhaps I just need the additional lumbar ones.
