I have a prominent wind whistle at hwy speed in my 250SE coupe. With windows/sunroof closed and antenna down I can faintly here it. With window open it is louder. With sunroof open and window open it is much louder. Sounds like it's coming from in front of windshield but hard to pinpoint. The seals at windshield, windows and doors have been replaced 5-10 years ago so they in good order even if not factory.
The thing is, I am familiar with the sound of air leaking past door seals but this sounds louder to me and harder to find. I searched to no avail...has anyone out there already been down this road?
