Well these days they use super expensive platnum plugs.
I doubt that when building the M119, or the M120, or the 600 Pullman's, they gave a flip about saving a couple cents on spark plugs, when they spent so much money on wires!
Or in the case of the Pullmans $1,500 seat switch's!
I think some engineer got a little to much freedom back in the day and built an ignition system around these cheap plugs, and they just followed his lead for years.
AFAIK all gas MB's called for non resister plugs until the M112/113 came out in 1998.
The FSM is pretty specific about what you can use, I prefer not to backyard engineer things. More so when the part they want you to use is the cheapest! Why should I go out of my way to research if a $5 plug will work, when they tell me to use the $1.50 ones in the manual?
You can do whatever you want with your car, and if from your experiance platnum plugs run fine in these go for it. But from my experiance I have never had problems doing what the FSM says to.
