You mixed it up.
Benz: A B C E S CL CLS SL SLK GL M R G classes
BMW: 1, 3, 5, 7, X1, X3, X5, X6, Z4, M series
actually different series/classes, there are some big difference between them especially on Mercedes. For c class that we see it daily, they usually are having big logo in the front. Except the classic version and the Elegance version. For e class, there is a new model that isn't walking on the street yet til now. That would be four eye (headlights). For s class, that can be really easy because it is really long and there is no other cars look like it in Hong Kong. Cls is four door. And the difference of Slk and SL, is that SL has more sharp edges, looks more sporty. For slk, is just a simple car that is two door and only having two seats. Gl is very special and there are not very much in Hong Kong, so it is really easy to recognize it. Also for G class. M is a SUV and it is high. R class is long and it has 7 seats as you notice when you look at it by side.
Bmw simply are having faces so you have to recognize it by the headlights and the length of the car.
