If your on the fence and reading this, just do it trust me ! My 2004 E500 not only rides better it handles like a completely different car. Some will say the air suspension rides better, yeah if you're into that floaty not attached to the road feeling and also when its working properly which on a 17 year old car is hard to accomplish. Install was very simple and took maybe 4 hours. I did not adjust the ride height and installed at the set height they came at and the car sits perfect for a daily driver. Soft/stiff dampening is set right in the middle and I cannot tell a loss in ride quality, only a gain on how much better the car feels on the road
