No I mean dirt when you go out and come back there is a lot of dirt in the back and in the folded top , I was thinking it blow by and not settle in the back.07 Mini cooper S convertible need suggestions, would a spoiler help keep dust out of mini with top down or up ? or is it just for looks , I have seen the one at Moss Mini or is there a better one ? I need to have front bumper painted could have both done at same time. Bring it on.
