I have recently purchased a 2003 Audi A4 3.0 Cabriolet and I'm loving every single minute with it. Last night, as I caught myself gazing at it before entering the bar, I noticed a couple a things with the cloth roof that I'll like to ask if it is normal. To the left and right of the back window, I noticed 2 little bumps directly in the center of each side. I don't remember noticing those bumps before and was wondering if its normal. Also, when inside, I notice that the beige cloth doesn't remain within the black border all around the sides. If you look closely, it originates from within the black border and then separates from it. Also, about midway through, there's a metal piece preventing it from staying inside the border. Is that normal as well?

I hope you guys understand what I'm talking about and I hope it is normal.

Thanks in advance...
