Thanks for the replies. Sounds like its pretty much the norm. Just makes it looks like you are really accelerating faster I guess. lol.

Yeah, now that you mentioned it on these when they were new, I remember my mom used to watch the old "Dallas" shows on TV in the 80s and I remember seeing alot of these cars (the W126 chassis) on the show (as well as the red 380SL convertible) and I think they squated down in the back on acceleration as well if I remember correctly.
