what is the original alfa romeo convertible window protective cover?I always use the original Alfa Romeo convertible window protective cover on mine. A little more time to use it, but I feel it helps save the back window. Doesn't offer the extra support a rolled up towel would provide. I may have to try that. A word of warning though, make sure the window and towel is clean and free of any grit, otherwise you may wind up scratching your window and not protecting it.
