I have a 2020, used to drive a Subaru and routinely drive a merc glk as well
2020 model is quiet. Wind noise above 120km/hr is pretty loud, but the a pillar fix solved it. I stuffed memory foam material from my old mattress topper there.
only noise left is upper a pillar, which is pretty quiet actually, and suspension noise. suspension noise is majority of the noise now. Maybe I’ll lower the tire pressure a bit when it’s summer.
