I guess you need to pay 10k more for luxury features that actually have a little thought put into them. Opposed to a Nissan with a big badge trying to compete with luxury car companies (Ie. BMW, MBZ, Lexus.)

If it doesn't endanger me or can be adjusted to have no effect on me, I'm willing to save 10k.

^ its air flow, plain & simple.
The windshield & roof profile are what shapes the air over the car.
The cars that have quiet SRs (most BMW) have a profile that lifts the air flow slightly above the SR opening & therefore generates less noise.
They also use a notched deflector instead of the flat bar that we have. This also minimizes the noise.
I might experiment with this myself...

nice DIY, you rock, this was actually pissing me off as I'd constantly open/close the SR depending on how fast I'd go/what roads-highways I'd use.
now i can make the most of that sunroof i paid for.
