All SL600s have ADS and the ride height is adjustable by you.
Stick your head under the front passenger (American) side and locate the sway bar. On it you will see a height angle adjustment scale. Rotate up or down to your heart's content (Bad A$$ low or Hoopster high).
Beware! Going much (really any) lower than the front factory setting causes the tires (optional AMG mostly) to hit the rolled fender openings (driver's side mostly) and excessive wearing of the bump stops hidden under the bellows for the upper part of the struts. Not to mention dragging even more parking blocks, curbs and ramps with the front bumper skirt and losing the tow hook cover.
The rear is similar (just follow the ADS body linkage) , but I don't know of any downside to lowering the rear other than the car looks squat. Some folks like the toed out, fat tired, body covering tire look. I've never crashed my rear tires to the rear fenders.
