I recently bought a 2020 GLE 350 CPO.
I was told that the car would be very quite and suspensions would be much better than my Toyota. However, I do not feel any difference in terms of cabin noise and suspensions.
Is there a way to test the cabin noise is as per standard or if I got a lemon? Same thing with suspensions.

Tires are probably the biggest cause of cabin noise, in addition to wind noise.
What tires do you have, and what are their conditions?

If there are other extraneous noises such as suspension clunks, they should be able to find and repair them.
Have them fit Chassis Ears to pinpoint noises.

I have Michelin all seasons I got from dealer. Tires are in good condition 7 mm tread left. It’s mostly the wind and outside noise. No suspension noise.

There were a spate of complaints about wind whistling around the outside driver's mirror. You might do a search for that. Do an advanced search, Use keywords, driver's mirror, whistle and the 167 forums.
You should get plenty of results.

We also have a 2020 GLE 350. Ours is much noisier than our previous ML350s. (forrunner to GLE). One noise they were able to fix was coming from the sun roof. But the 4 cylinder engine is much noiser than the previous natural V-6. Road noise is also much louder in the cabin than previous MB's we owned. I even had the dealer check that none of the shields were missing under the car. Seriously considering trading it.
