Dealer Service

So I'm trying to decide which dealer I'll ultimately buy a Volt from. The dealer closest to me does not have the exact configuration I want, while a few chevy dealers away they do. And while price may ultimately be the deciding factor, I also worry about service -- particularly given some of the strange occurrences with this vehicle that may require more than just regular maintenance, or "normal" warranty stuff. My concern is whether, if I buy a car from a more distant dealership, will my local guys treat me right if I have any significant problems (like something that might require a loaner)? Particularly, will they even provide me a loaner if I didn't buy the car from them?
