How Quiet Is The Interior ?

As I mentioned in a previous post, I will need to have my driver door aligned...A lot of wind noice, etc...

What should I expect after they fix this? Is it really quiet or should I settle w/ some wind noice along the driver door at say...50-60mph?

It's pretty darn quiet. Just a whisper of wind noise on mine. Nothing intrusive.

Mine is very quiet inside as well, which is one of my favorite "features" of this car. I turn on some tunes, lock out the world and enjoy the ride!

Mine is whisper quiet. Test show the C at 63 db @ 70mph compared to 65 db for the DeVille.

You should expect to be driving one of the quietest cars on the road. DC made the glass 25% thicker to help reduce outside noise.
