Re: No one's wearing a bra?
I have Chrysler bras on both my 05's and the only complaint is that I can't take them off with one hand, like back in......wait, that's another story.
I agree they can hurt the paint if you don't take precautions. But first off I rarely run the cars in the rain so mud and crap don't get under them and I remove them several times a summer, vacuum them real well, and wax multiple extra times where they touch the body. No problems at 32k with the roadster. Best of all, with a little Armorall dressing, bugs wipe right off. I do not enjoy being on my knees scraping heat-hardened bug splat off the grill work.
I've had a bra on my A6 for 100k miles with, admittedly, a little roughage on the bumpers from crap getting underneath. But it is mostly a winter driver and when you're stuck behind a truck on an icey, newly salted road, having your bra on saves a lot of damage to your front end. And heaven help you if you have to pass a sand/salt trunk at 70 mph.
