You cant tell the diffrence to well in the pictures, But I have seen rims in tires places that have the same darker color as the 3.5 rims. I think most manufactures are calling it Hypersilver. With the right color car they look SWEET.
that pic of the 2003.5 wheel is f'd up. doesn't look right. It almost looks like a 2003 wheel. Not surprised though, I own the wheels and I can't get a proper shot of them either. The mirror surface reflects light too much and f's up the camera.
I dunno, a little cropping and a smudge of the background and that's a pretty decent pic... I'm thinnking of changing my silver '03 MSP rims for the '03.5's one of these days... good thread.
