When you consider that the overwhelming majority of the time (especially when doing spirited driving), people drive cars with no passengers - it make sense to engineer the ride height to account for that majority of time.

To the one who asked "what happens when a passenger gets in?" - clearly, the balance would be offset somewhat again. However this is a better solution than it being uneven during the aforementioned majority of the time when only the driver is in it. You'd have to go with one or the other, short of getting a costly/complicated/heavy self-leveling suspension.

And it's not a new concept - drivers who do autocross and other auto racing routinely get the suspension setup calibrated by a shop while siting in the driver's seat. Also some cars come from the factory with spring rate that are a bit higher on the front drivers side for this same reason. Also, the aftermarket suspension I bought for my last car had specific drivers and passengers side springs in front - for the same reason.

Lastly, I think the comment about the ground not being level is a good point - it''s probably safe to say that almost no ground is perfectly level, even if it "looks" level. Driveways are not built to tight tolerances in slope/angle. Neither are parking lots, alleys, roads, etc. The garage floor of a house might be best, but is still going to have some built-in slope by design. The ground alone can potentially provide more of a perceived unevenness in ride height than the actual suspension.

So based on all that, I think considering this to be an "issue" is a bit dramatic - it's a "feature". And a good one.

What brand of coilovers did you go with, impressions?[mini thread-hijack, sorry]

I wonder what they figure an average person weighs? I guess i'm not evening it out at 175lbs.

You can see it slightly tilted in that last shot

however there's no way in hell bmw engineered these cars to sag to one side when parked. I work at bmw and never seen a e60 or f car come in sagging. There would be a ton of very unhappy customers.

My first thought was a broken spring, I checked and found nothing. My next thought was maybe the sway bar got jammed slightly twisted in one direction. Then I thought, surely id feel that around corners. I haven't actually spent time looking to find the problem, but I do know this is not factory.
