lol...i'm sure i won't be needing that. it's hard to even find a 2 mile stretch of freeway to get to 155 in LA.

I disagree.

Frank, that is why you should do some canyon runs down in San Diego, or over in Malibu....

i'll keep my car in the garage for a while now...u should see my car. in only 6 month, my car looks like 1 yr old.

Hehe, that is also why you should not have driven her to school everyday! It's all good though...

the thing is, i don't. i drive on weekends a lot, but main thing i have to blame is my cousin came from taiwan back in june. probably 3k miles are from driving my cousin and her friend around. Vegas, SD, universal, disney, hollywood, etc...

Ian are you sure in this?
Well i race on the freeways a lot and i got it three times already. First 1 @ about 140, second one at ~149-150 and the last 1 at 130. I don't think this sound is someting special that was planned by AMG or MB. I guess this is air coming from the clim. contorl system. I don't get this sound usually when i drive without my AC on high speeds or race ( when i race its alwqays off ). This far i got this sound twice when my AC was on and once when i just turned it off. Its freaking me out. Looks like my baby C screaming in pain. God make it stop. Im going to service soon and im gonna ask my service advisor to check it out, but what they gonna do? Im pretty much sure they won't take my car on the freeway and speed up to 155 5 times in order to find out.

Hi Rustboy,

that was an information by a german C 32 forum. But I don´t think that it´s air. And don´t drive that fast in the US
