Looking to hear from people who have or have heard both Bose and the standard audio system long enough to comment on the differences. I have heard the Bose during a long test drive and it was excellent. However, most of the Cayenne I am coming across are w/o Bose. Some salesman I have spoken to say that the difference is merely the label and that the standard system is excellent (i.e. can play it as loud as your like without any distortion).

I would rather hear about the difference from the people here who actually own these vehicles rather than the salesman who's selling the vehicle.
