TANK

I had two 123's, one auto and one manual. Both of course had external oil coolers. Even in very cold weather, once warmed up and driven, their oil coolers would get warm. I don't see the external oil cooler as a negative at all.

Some time ago I had a discussion with a Porsche factory mechanic regarding oil and engine oil capacities. He cited the 240D as an example of an engine of long-life for many reasons including the external oil cooler and the extra oil its system added. Porsche has used large oil capacities for years, just like Mercedes. His opinion: one of the keys to long engine life.

My 2 cents.
