Has anyone had a car shipped from CA to the East coast

Make sure that you put plenty of insulation in with your car when you pack it in the box, so it doesn't get damaged in shipping...
Lol, but in all seriousness
If the shipping company is any good, they'd have wooden blocks bolted down to keep your car in place as well as straps just in case. Only thing that can affect you is the container doing flips.
