When car is stationary it vibrates in drive but quiet in neutral on 2000 Mercedes-Benz E320

Just bought a 2000 e320. When car is stationary (for example at a red light) it vibrates quite loudly in drive but nice and quiet if I put it into neutral. It also sounds fine in reverse. I suspect engine mounts. I am looking for a way to verify this or get an idea what else it can be

It's possible that it would be the mounts, are you experiancing any other drivability issue or has the check engine light come on at all?

Thanks for the reply. I ended up getting the mounts changed and it did fix the problem
