What is the difference between Cic/ iC/ Ci trims of BMW 3 Series....?

Answer 1

First of all, the "Ci" trim refers to the 2-door coupe models like: 330Ci, 325Ci.

Following that with another "C" indicates a convertible, for example: 330Cic which is for 330Ci Convertible. However, since all 3-series convertibles are 2-doors, sometimes people drop the "implied C" for coupe and write: 330ic for the convertible model.

"Officially," BMW uses the "C" only to designate the coupe and spells out the "convertible" for convertible/cabriolet models.

Hope that helps.

Answer 2

for 2007 they have dropped the "c" designation altogether. it's now a 335i sedan, 335i coupe, 335i convertible, and the same for the 328. Although they have the "x" in some models: 328xi sedan, 328xi coupe.
