Interesting comments about the M103. I find the engine perfectly suitable in my 300CE. Then again it is the smaller body. I also get no less than 20 mpg in mostly city driving. I would agree though that the larger body W126 does seem better suited to the V8 if you had the choice. I wish the rear end was geared lower. 3k rpms at normal highway speeds is not ideal.
