Fair enough and my assumption may have oversimplified. Car dealers are in fact protected by state dealer laws. All that being true, if the OPs experience has been that his dealer is acting purely as a middleman without the service that some of the best provide, I still do not see his questions as being over reaching. And prepping oneself for a negotiation is prudent in my opinion. Further, the reduction in audio dealers Is not dissimilar to a consolidation in nearly every space- maybe even more so due to a shrinking customer base, suppliers consolidation causing a change in focus. I don’t intend to create argument- my initial point was that the OP has a right to gain as much knowledge as possible to negotiate his best deal.
