From your description, I would be uncomfortable with the dealership. I hate high pressure salespeople, as well as disinterested ones. I will walk away from such situations. Its your money, and they should appreciate a chance to earn it.
Last niche car I bought, I visited 5 dealerships(50 mile radius, 2 states) before finding a place that was comfortable. It was relatively rural, selling mostly pickups. They were happy to work with me to get the car I wanted at MRSP.. of course , I consider that a premium price for a low volume, high demand car, but I won't spend a penny more, and i was unlikely to to get it much lower. Plus , I don't let them put their company logo on the rear... I was the only one they sold that model to.
