Hi Steve,

you are right, I pressed down at the back of my W126 and I can prob. press it down 2 inches and it might go up by 2.5 inches and then go down that half inch and come to a rest. Don't hold me to the inches, but as a rough idea of it's movement. It is probably easier to see when somebody else does the pressing and you see it from the side.

Regards
