Is anyone else having problems with the wheel caps falling off? I have an XC90 2.5T with standard wheels and the small black wheel caps (with Volvo written in them) are falling off. I have lost two now and they are $AU30 a pop. Also during a service I was told that I needed new wiper blades, no problem I thought until I was told that would be $AU100!!!! Does anyone know of an after market pair that suit. I think the problem with "normal" after market blades is that they are not the same shape. I am also told that you can just give the old blades a light rub with some sandpaper and get more life out of them. Any comments on either issue? Cheers, Mark
