I bought a 2020 E63S used a month or so ago. One feature that I would have liked, but don't have, is the acoustic comfort package. I'd like the car to be quiet and serene on the highway and, right now, I get significant road noise.

Has anyone tried to replicate at least some of the acoustic comfort package aftermarket? Is this feasible? My understanding is it includes additional cabin insulation and an acoustic membrane in the windows. Swapping windows seems like an expensive proposition, but surely adding insulation can't be that difficult? Where would the insulation go?

Just curious if anyone's already done the legwork on this.

Thanks!

According to the MB description of the package most of the added sound deadening is in the floor.

Here at our local MB official forum, there is one guy who changed insulation on his w213's. It's written in bulgarian, but pictures can be helpful if you will going to do the job.
