I just purchased a 2003 SL500 with 46K miles. I have noticed that when i turn the engine off at open the door i hear a hissing sound inside the cockpit. As soon as i close the door the sound ceases. What am I hearing and do I have a problem? Thank You

That is agreat car. I don't belive you got it with such low miles.

The sound usually comes from the air vent. A similar sound can also come from the radio if it is aftermarket.

I wouldn't worry about it. At least not yet. :)
