Absolutely agree with having the buyer pick and assume responsibility. Tell him you are responsible until the X5 is on the truck but then it's between the driver and the buyer. That's what I did when I sold my M3 and shipped it to Chicago. Also, take lots of pictures of it at the time it is being loaded - inside and out. If it arrives damaged you can show that it was fine when it went on the truck. The interior shots are important because I have seen many cars on transporters with windows open. Dust? Rain?

Most places you see advertising as auto transporters/shippers are simply brokers who will tell you all kinds of wonderful things about how conscientious they are, etc, but then sell off the job to some random trucker. There aren't that many companies that keep it all in-house. Just FYI.
