I just purchased a 2007 xc90. I love it...but it is hard to see out of the back due to the second row headrests. Is there any way to remove them? I fold the headrests down normally whenI drive,and it makes a world of difference, but it looks kind of funny.......then when I have backseat passengers I have to fold them back up and Im back to not being able to see behind me again. What should I do?
