I just spoke with the driver who is picking up the car. He specializes in higher-end models and has quite a bit of experience with 911 and 356 Porsches. He's hauled groups of 4 at a time to car shows and does dealer transfers as well.
It'll be on a 4 car hauler flatbed with nothing above it. First to go on and first to come off. He used to live in my area so he knew the directions without even looking it up. I feel much better after talking to him in person.
I'll have it in my driveway 1 week from Saurday.
