Here are my two cents...
Walter,
Seems to be stick shift, I cannot find a dipstick for the automatic transmission on the pics.
Like the idea of a 6 cylinder Diesel in the SLs engine bay since our cars have 6 cylinders too.
Can't see all the intake ports and fuel lines but the head looks long - so 6 cylinder. Thus, Mike, it must be a W124 300D
3.0 instead of 2.5 (which is a 5-cylinder). Therefore, the owner "had to/should get" a 300 SL badge instead of 250 SL.[:0]
250SL "aftermarket trunk signs" can be obtained by cutting down the "E" from the 250 SE badge into an "L" .
However, this is visible afterwards even with a lot of polishing.
Daryl,
Cannot personally agree with the
"but there is nothing that matches the aethetics of the fuel lines wraped around the front of the Mercedes Benz 113 engine. I plan to keep mine as is".I think the original valve cover with the right side indentations for the injection nozzles together with the intake manifold are unrivaled beautiful. Was for me one reason to buy a Pagoda!
I plan to keep my M127 II as well.
Just my 2 cents.
