I was in Miami a few months ago and saw a E500 4-matic Wagon. Black on tan w/ an 75yr old driver who had no idea why I was drooling on my window. Man I would love to give that V-8 everything w/ that 4-matic kicking in all the corners! Can you imagine it in the snow!?!?!? Absolutely beutiful car.
As far as the w124 I know they did make an AMG stick shift wagon, but I don't remember if it had a V-8.....somewhere in the back of my mind I seem to remember that there was some kind V-8 released at some point...have to check my books....I think they made a few w123 V-8's too...hmmm
