Does anyone know if the 85 300D is the same engine as the 85 300SD? I am trying to make a decision here -- I know of 2 - 300D's with 90k to 120k and a 300SD with the same mileage.
Anybody with thoughts in this area would be appreciated.

Both cars are great but I would go with the w126 (300 SD). It’s a more modern design. The w126 is larger and less prone to leaks and ACC problems. And the fuel mileage is not that different.
The engines are fairly interchangeable, but you will have to do some minor rewiring (gauges and such a tad bit different). Did the same swap in my 300D, and the new engine runs like a dream.
This is an older thread, you may not receive a response, and could be reviving an old thread. Please consider creating a new thread.
