M for Monster !!!

[Yinka Gbotosho]

I am sure this question has been asked more than once before but I cannot help but ask. What is the meaning of ML? In fact what do those alphabets represent. C for Coupe? E for Elegance? S for Super or Senior?
Even if we assume that the M stands for Monster, what does the L represent?

I love my ML even if I dont know the meaning.

I believe the manual said:
(M)ercedes (L)ight truck.
