I am looking to buy a g37x sedan within the next two weeks. My questions is does it matter if I buy from the dealership or not? I was oriinally only looking at the dealership, but recently I have been browsing the internet and noticed other dealers had the cars priced a few thousand below what infiniti dealerships were asking. Will I still get roadside assistance, etc with a car not bought from a dealership? What about loaner cars when I take it in for service, all of this is important to me.
