Car is closing in on 10,000 miles and has developed a vibration that I can feel through the gas pedal and even from the passenger foot well.

Seems to be most prevalent at 2400 - 2500 rpms

Any thoughts ?

It is extremly annoying, anybody else experience this or better yet has had this problem and got it fixed ?

if its that bad the dealer should notice it. Take it to them before it becomes a "real" problem

Don't tell MB you have the Vibrator option .. that will add another $1300 ...

So nobody else is feeling vibrations in their C coupe?

Maybe you need to be more specific. Does the frequency change with engine RPM or vehicle speed? Does it vibrate with the car parked and you rise the RPMs? If it only does it on the road, pop the tranny into neutral. Does the vibration go away?

Could be a simple as a tire out of balance.

I get some sort of front end wheel vibration/thunking between 25-35 MPH in the sedan. Don't know if its the tires or not.

Try switching AC on/off. Any difference? I can feel it when the AC is on, through the gas pedal. Not much, though, and I'm not worrying about it as I had experienced this with other cars. It may even go unnoticed if you are not paying attention.
