It clearly has an impact on both engine life and transmission life. And speaking of transmission the E320/124 is always a 4 speed while the S320 is always a 5 speed - 722.5 through 1996 then 722.6 in 1997. The .5 has a decent reputation but is an expensive rebuild whereas the .6 has a horrible reputation and is an expensive rebuild. I see that Sun Valley rebuilts are now the same price for a .5 as for a .6 - $2750 - the 4 speeds only $1250.

Where are you getting your weight figures from? Is that a long body or a short body car? Are you comparing an S320 with an E320? The V8 140's obviously weigh more.
My Brothers 1983 300D weighs 100#'s less than my 1982 300SD. The SD blows the doors off of the 300D speed wise. Its interesting that Mercedes engineers would suddenly forget about weight so blatantly in their designs.
