Just wanted to note that there was a silverish blue W126 300SD on "Simon and Simon" today, being driven by the chief surgeon of a hospital who tried to kill one of the Simon brothers. It was a 1984 year episode, so it was pretty new. Instead of changing the engine noise, they kept the original diesel engine noise. That was the highlight of the whole episode to me.
