My mother in law is moving from NY to AZ. She wants to ship her car. Her household mover offered to arrange shipping. The mover worked with a broker to make arraignments. The shipper, or possibly broker, that she was working with has become problematic and unresponsive to calls or email. We are now trying to help her out, but all our googling gets more of these brokers. Does anybody here have experience with a reputable auto transporter that you would recommend?
