My opinion is that 99% of brokers are a BAD deal. They just farm out to someone who farms out to someone who farms out to someone.
First problem is that you car is guaranteed to be moved from truck A to truck B and probably to truck C throughout the journey. And it may sit in a lot somewhere for days. Of course, they won't TELL you this.
Second problem is if something happens to your car its almost impossible to go after the right person. The guy that delivers it says "oh that must have been done by the first guy" and then that guy points the finger back. LOTS of bad stories out there about brokers.
Bottom line: You just spent $30k, $50k, $70k on your baby. Step up and spend a few extra hundred to have the job done right.
Or fly out and drive it back!
