The dealeship told me the mounts are collapsed.
I pressed the gas while on drive and reverse holding the brakes and I could see the motor flex up down on the side.
Also the moment it is on drive or reverse there is some vibrations up front but none on the steering wheel.
Thoughts please!

Two engine mounts are not urgent parts to replace ASAP.

It chunks rattling on the bumpy road.

You can wait months. i replaced at around 190k km odo.

Thanks I only hear vibrations while on D/R. Not sure if I'll change them now.
I was quoted $838 at one shop and $1012 at another.
Is this reasonable?

No idea on ABC shops quotes.
About 3 hours job i guess.
Check MB dealership and compare what you want.

Cheapest way is to buy parts
and bring them to a garage who is willing to install customers part without the part warranty.

Replace failing parts before you are replacing more broken parts. You don’t want the bolt to break from constant banging, and then your engine to hit your hood while also breaking other plastic hoses and clips along the way. You can let a ball joint clunk on your suspension too, and some people have their wheels fall off in the middle of the highway. Don’t listen to advice that tells you to neglect problems you know you have and clearly went to a mechanic to diagnose.

Is it 4MATIC? 3 hours is not too bad if true.

Yes, my vehicle was serviced for that gas leak on the high pressure side that most mb have especially when it is really cold outside. Lucky it was still under warranty. Anyhow that's when they noticed my mounts are collapsed. As I press on the gas I see the sides of the engine go up and down. I think it is time to avoid issues like you said. If I wait for knocking noise and major cabin vibrations I'll end up having to fix way more as a consequence.
