We just snagged a new BMW X3M from a BMW dealer in Missouri (we're in Wisconsin); couldn't have been easier. None of the dealers in the Milwaukee and Chicago area would realistically play ball price-wise. Filled out the credit app online on a Tuesday, they overnighted paperwork Wednesday, we signed and sent back Thursday, they stuck the car on an auto carrier on Friday, it showed up outside on Monday - just like an Amazon package. Was really cool and I feel like I'll have a hard time transacting at a dealership physically after this experience.
Can't speak for the trade in process as we didn't trade anything in but I have to imagine it'd work similarly. The BMW of ours that this replaces was sold to a buyer online out of state who's having it shipped.
With the internet and technology these days there's no reason not to consider a great deal in a different part of country.
