Acceleration/Vibration Issue
Hey guys. I have an issue that came about recently where the car will vibrate pretty drastically under acceleration around the 2K RPM mark in different gears. It is almost a similar feeling as if you were to touch the rumble/wake up indention on the edge of the lane on the highway. I have not looked at the driveshaft but I plan on potentially doing that this weekend.It almost seems like it would be something more in depth.
Car Info:
Year: 2009
Make: Mercedes
Model W204 C350 Sport
Mileage: 130,000 Miles
Has anyone had anything similar like this happen before or heard of this type of issue?

It's likely your trans and engine mounts. My '13 C250 is at the dealer right now for a Service B (laziness to find an indy after moving) and they recommended mount changes since they "sat low." $1300 in parts and labor. 
I'm at 146k miles. You might already know how to diagnose it, but have a friend (or camera) look at your engine with the hood up. You sit in neutral/park and put it to about 1.5-2k RPM. See if the engine moves drastically or at all.
If not ,then check out your transmission mount. Jack up or roll your car on some ranks and take a look.
There aren't many videos I found on youtube for W204 mounts, but I assume the process is pretty similar across all models. I'll probably change mine if I notice anything worse, but keep me updated with yours!
