Also, kind of funky is how you start the car ala 7-series. Put the plastic "key" in the slot, and put your foot on the brake, tap the start/stop button....

I kind of like the old way....put in the key and turn it.
Also, at night, when you unlock the car with the remote, there are bright white lights illuminating underneath each outside door handle. Glad they extended that idea from the E53 X5 with having the bright white light underneath each outside mirror.
Also, the new Valeo wiper blades (the one with the infinite number of contact points) worked really well in the E90.
