You think the 826 are bad? The wheels on my wife's E46 were the worst, especially since she is a typical driver and I didn't have the opportunity back then to wash the car weekly (before we married) and so it was quite a chore.
The only upside was that all of the slots between the spokes were the same size. So once I found a brush that worked, it went fairly quickly.
