Almost correct:
SLK - Mercedes Miata
C Class Coupe - I believe slightly shorter than my E coupe, not pillarless, but same interior / seats. Dash is slightly different.
E Class Coupe (Replaced CLK Nomenclature starting in 2010)
CL - which to my knowledge is actually S Class based,
4 Seater
SL - Mercedes Grand Miata
2 Seater (Europe only optional childrens seats in rear)
SLR - Mercedes Grand Grand Fancy McLaren Miata
Don't forget, there was actually an E Convertible as well
