Thanks for these helpful comments.
One other question that I think someone has sort of mentioned... is there any danger of bits of the external part of the roof getting scratched when the roof folds (when the rear section is placed on top of the front section)? Also, is there any danger of the interior parts getting dirty (if the outside areas are dirty for example). I can't recall the interior bits of my old Z4 roof getting dirty in any way, but wondered if any E93 owners can comment. Sorry if these seem like dumb questions...
