Corvette comes with a Bose Premium sound system, as does the Mercedes and again, if you aren’t listening to it in the right format it doesn’t matter.
Edit: Allow me to add on and clarify my point. My original argument was that he said Bose and Harmon Kardon were the best money could buy. ANYONE who has heard music played through a system that is truly the best money can buy would laugh at that statement. Bose and Harmon Kardon are over-rated in terms of what you are getting for your money. Is there a difference between a cavalier sound system and a Bose. Yes. But it is far from being the best, or even a very good system.
