The differences between the 300D and 300SDs are that the 300Ds were the E-Class whilst the 300SDs were the S-Class of their day. As a general rule the S-Class should be the better drive but in a car of this age more will depend on how the vehicle has been looked after and treated. The 300SDs had a turbo where the 300Ds didn't unless stated on the badging, this is where things get confussing; The 300D was a non-turbo saloon, the 300TD was a non-turbo estate, the 300TD was also used to badge some turbo-diesel saloons whilst the turbo-diesel wagon (and often saloon) was identified by a 'Turbo-diesel' script on the right side of the boot or tailgate.
The S-Class never officially had an wagon, but a few coach builders such as Crayford of England took on the projects. These are rather rare and how many were made from the 300SD is another story. Mercedes had intended to put in a 6-cylinder diesel into the W116, but the engine was no where near finshed when launched in 1977 so a five cylinder OM617 from the W123 300D was coupled upto a Garret turbocharger. As a point of interest it was Garret who turbo charged the 200bhp C111 diesel of 1976. The OM603 6 cylinder diesel wasn't available untill 1985 in both the W124 E-Class and the W126 300SDL, or in the guise of the 350SDL of 1990.
Personnly I'd go for either the W123 or W124 Estates as the coach built ones may be hard to source parts for (glass, tail lights etc.)
