Here in the Southern tip of darkest Africa, when advertising or writing about these cars, it is generally acceptable to add an A at the end which denotes Auto Tranny. As S-Class mentioned before this has been general practice since the 60's/70's untill today, ie 200A, 200EA all the way upto 500SEA, 560SELA or even S600A.
Using that reasoning, it would be safe to assume then that you also have 200M's, 200EM's, 350SEM's, S600M's etc. True/untrue ?
