Ah, that explains it. When I was looking at the 535i xdrive wagon there were essentially no option choices any more -- Executive package was mandatory and that was it. I love the HUD and night vision options (also ventilated seats -- another great but almost impossible to get 5 series option). Sounds like a great car you've got. However, I've heard it's v. difficult to see the HUD with polarized sunglasses. Do you find this to be a problem?
Absolutely true - polarized sunglasses do not work well with the HUD. The only way to see it is to tilt your head to the side, and then it's only faint. I found Serengeti sunglasses are fine as long as they're not polarized. Also wished more controls were on the display, such as the gear you're in when in manual mode.
The ventilated seats are nice in the summer - helps prevent a lot of heat buildup with the leather. The only thing I would change is to have had the controller, screen and GPS system from the 2010 model - looks much better. I've been trying to find out if I can get it retrofitted.
The adaptive cruise control is also good for "most" situations, although with some drivers around Toronto, you'd best have your foot prepped to brake as it can take a couple of precious seconds to recognize a car that's doing some dangerous maneuvers. Great for long stretches on the highway with reasonable traffic (and drivers).
Also love the versatility of storage options with the wagon (the safety net actually can be used with the seats either folded down or up to protect the occupants). There's a fold up for putting grocery bags in the trunk (easiest if opening only the glass of the hatch).
The extended moonroof is nice for the backseat passengers, the comfort access can be problematic if put in a pocket any denser than sheer, but generally it's helpful, especially with young children around and your hands are full.
Overall, I have to say that it's a well thought out car - practical and fun (if a but costly). If the problems I've had are now sufficiently fixed, I may opt to up the horsepower through Dinan when the warranties run out.
