330ci pre-facelift differences?

[twoblacklines]

So the more time I spend casually looking at 330ci's for sale, the more I think "why don't I just buy a pre-facelift?"

I actually like them a lot especially the wheels they come with. And there are more manual ones than manual facelifts.

Now I know the following changes

headlight shape therefore bumper?
headlights don't have projector lenses
rear lights are not LED

Name changed from m-sport to sport or other way round.

Where there any other changes or all cosmetic?

Are there any options for projectors in the pre-facelift headlight assemblies...because I would like xenons ideally.

I'm thinking buy one of these for £3500 and spend the other £5k on a nice watch or something?
