These pictures might help. Note: my car does not have the fins on the rear of the diff.

Why "3. GOOD GOD NO!" to my question #3? What is this silver metal beam running from side to side? I seem to remember a friend of mine jacked up the rear passenger side of his Benz by jacking that bar close to the rear passenger wheel.
The suspension components are too delicate and engineered to support the cars weight in a particular manner. The body sits on the sub-frame via 4 rubber bushing. The aluminum sub-frame is a pretty substantial piece.
Page 21 of -->http://www.e60.net/information/E60_Dealer_...Information.pdf shows the subframe in detail.
I would not lift from the differential as its mouning to the subframe is not designed to support the wieght of the car.

The fins I've seen have been on the back part of the differential (the silver piece that has the drain/fill plug in my picture); some hang down below the bottom of the diff, and some are even with it. For those that hang down below, I'm not sure where you'd place the jack. For those that are even, I'd put the jack in the same place as I have in my picture, but I'd be sure that I was placing the pad on the diff and not just the bottom of the fins.

I like number 3. It is a solid structure however.... my concern with lifting from the center is "balance".
I am very cautious when lifting and if the lift was not straight, I'd probably wimp out and lower the vehicle, fearing the vehicle might "slip-off" the jack before i get the stands under both sides.
In fact, I'd be hesitant placing the jack stands under the vehicle if it didn't go up straight.
Then i'm back to lifting from 1 of the 4 jacking pads and then placing the jackstands under the vechicle, one-corner-at-a-time (placed under the subframe, biased left or right depending on where i'm lifting from).
I have 2 floor jacks which allows me to lift 2 corners simulataneously. Seems safer than lifting from the center (front or back).
If you have the spare $$, and you do since you have a BMW, get 2 floor jacks and have fun.
