I had some ordinary type wiper blades on the car when I bought it and they were ok but look clunky.

I saw some Goodyear aero wiper blades in Costco, and couldn't resist.

For anyone interested, you need a 19" and a 22" blade for the E46.

The blades are excellent, ultra quiet and an effective wipe across the whole blade, they are also very tidy and smarten up what was once a cluttered area. Couldn't recommend them more.
