Glad to see I'm not the only one
I guess it depends what country you are in but in the UK if you drove into a customers car park with a porsche etc they tend to think they are paying you to much so a certain level of discretion doesn't hurt (and 90% of people won't know any difference between a 4 door m3 and a normal one I expect).
Has anyone seen a picture of what the side vents will look like debaged?
