Ask if there will be someone (an agent, or customs broker) who could assist with customs clearance and unloading at the country of destination. Also, do your homework on customs duties and taxes that may be due at the country you are shipping the vehicle to.next
If you have a choice of a door-to-door pick up/delivery option - take it. The old terminal-to-terminal feature only makes your vehicle that much more likely to be stolen or damaged. Dont work with auto movers who will make constant stops at warehouses or cant bring your vehicle to your door.
