Thanks for taking the time to respond, but I don't think you really answered the question. Back to your analogy, if all the car dealerships in your area are all of one brand with different models it doesn't matter which car is 'assigned'. They all come off the assembly line with the same chassis. I actually did meet with 2-3 dealers this last time before choosing this one. A year ago the dealer assured me that this model would work for me, though I was skeptical because I had more car knowledge than the dealer. So after a year do you look to trade in? Or do as suggested and talk directly with the dealer about the dissatisfaction? Or both?
But the original question is whether the dealer is pushing their brand because that is the only brand they know?
