I'm going through the same decision making process as well. Went back and forth with an Audi S8 and the new, at that time, B & O system. It was between three and four grand, as I recall.I don't keep vehicles very long so I have to at least consider resale. The dealer told me back then that the B&O wouldn't be worth much for resale, and today, it isn't.

 

Good to hear I'm not alone. Let me know what you end up doing. I'm leaning towards nay since I'm not really an audio guy.
