Had some time over the weekend to start tackling the noise reduction project on my 420SEL.

The door seals all seem fine (quite flexible and snug); but nonetheless, I tried reconditioning them with some silicone to see if it made any difference. In a nutshell, it didn't.

Next step: replace the seals.

If that fails, I guess it's time time invest in some Dynamat...

Stay tuned!
