Both of the vehicles that we have purchased there were used, so I am not sure about their new car sales. I do know that Caleb keeps busy, they aren't a large BMW dealership (compared to Detroit/Ann Arbor) but they service a large area. Scheduling appointments for service you can normally get in the next day, but the sales staff and the service advisers pretty much don't sit still as far as I can tell. As far as the out of state check thing, your guess is as good as mine. But I am sure they have a good reason to possibly turn away paying customers.
