After agonizing over whether to cancel my order for an '06 550 and order an '07, the wait (and the 72% residual) got the better of me, and I decided to just go for the 06.
Well, I picked up my car (finally) yesterday (original post was here: http://www.bimmerfest.com/forums/sho....php?t=127194), and already have 200 miles on it (not worrying about the lease yet

.
Silver-gray/black, pretty much everything other than HUD, active cruise, and fold-down seat.
Here are my initial impressions:
- Driving/Driveability: WOW! This car just begs to be driven and pushed. On the 73 tollroad to Laguna Beach yesterday (a great, generally wide open road), I was up to 100 without really knowing it (my wife didn't know it either - til she saw the speedometer

Turns that my MBZ E500 would have slid in, the 550 is steady and just seems glued to the road. Incredible.
- Comfort: I highly recommend the comfort seats (anyone getting an 07 sports package won't need to decide). The seats are incredible. I've had a '98 BMW 540, a 2000 Lexus GS400, an '03 MBZ E500, and now the 550. I could never really get comfortable in the 540. The Lexus felt great, but didn't have the support for long drives. The MBZ (w/ multi-contour and drive-dynamic seats) had the most comfortable seats in a car I've had - up until now. Also, there's a little bit more room in the back-seat than in the MBZ
- i-drive: Well, the jury's still out here (of course, I haven't read the manual, so this may help). I want to get: the satellite radio station persistently in the left pane, and use the right pane for different displays, etc - can't seem to do this. And it seems that whenever I go to select another sat radio station, i lose the display of what's on. It's easy enough to learn how to use idrive, just may not be able to do everything i want with it. Additionally, the system seems slow to start (and it's start-up times are inconsistent). I'm wondering if this is specific to my car (not a problem already!!), or if tihs is just the way it is in the 550's.
- Storage: Well, here's one place where the 550 loses. I had a much larger center console, and much larger door-pockets, in the Benz. Very limited areas to store stuff (CD's, my blackberry, etc

. Additionally, it's sad (but not surprising) to see that BMW still hasn't made a suitable cupholder. I haven't tried with my Starbucks travel mug yet - but put in the cupholder yesterday and it seemed rather floppy. Anyone have any suggestions on good sized coffee mugs that stay put? (I need my morning coffee).
- Sound: GET the premium sound. Sounds great, and very adjustable. Other folks have said that the Sirius doesn't sound that good -- I don't know, on the 200 mile drive yesterday, Sirius sounded great (not as crisp as a CD, but pretty darn close).
More as I drive it

A few more questions:
- Any way to program the car so it locks when you step away from it? (I have comfort access)
- I had seen somewhere that it can be set so you don't need to pull on the handle twice to open - anyone have instructions?
Thanks all.
