I have the elegance spec W210, with the comfort suspension (lots of ground clearance, long springs I guess). The car has 179000 miles on, is nearly 10 years old, and I wondered how much bounce there should be when pressing on the corners of the car with my bodyweight?

If I push it hard down, it bounces back up, past the resting point, and then back down and comes to a rest. Same on all corners.

How much 'bounce' should there be? Should it return instantly to the resting point, or should it oscillate a tiny bit?

Theres no bottoming out of the suspension btw, no crashing over potholes or anything.
