Guys can you help...when I drive faster I hear a whistling wind noise come from behind behind me.

Not sure if related but my passenger door shutting sounds rich and solid whether wether window is down or not. My driver door sounds like a cheap vehicle when I shut it with the window down. Kind of like a tin can, rattling noise.

Thanks for your advise guys and thanks for pointing me in the right direction..i guess the sound of the door is what it is but the wind noise is definitely annoying.

 

Here's a video that may help , it's Mercedes r170 but the mechanics should be the same as our Crossfires
