I used these guys to ship my 930 from Denver to PA.
A Across USA Auto Transport
$775 door to door.
Everything went smooth as silk.
Ordered the transport on Saturday; Driver picked the car up on Monday; Car was delivered to my house Thursday.
Communication with transport company was excellent.
I had the driver's cell number and talked to him several times over the 4 days in transit.
One thing to watch out for when getting your car shipped is to make sure they don't terminal it. That is, it doesn't get taken off the trailer and put on another trailer at a terminal.
