well i have done this!!
first off it's a bitch to get a container, if you go for half a container then you are at the mercy of the exporter and the importer.
if the car nis registered in the U.K. then you have to get permission to permanently remove it from the country.
if it is not registered then you do not so make sure it has no frame number that is logged in with the DMV in Swansey. i am not saying it can't have a number.
get a freight forwarder to put it in a container at the port or a container base, usually located in a city, a whole container or a part of a container, just deliver it to them and they will do the rest.
when it arrives in the U.S now your problems start, any frieght forwarder can grab your container and hold it hostage, they will contact you when it arrives at their depot and make up some ludicrous fees before they will release it to you esspecially if it is only part of a container.
if however you can get roll on roll off, you may be able to save a fortune, drive it to a prearranged port like folkstone and they will ship it and give you a bill of laiden, when it arrives the shipper or the port manager will contact you, go to the customs shed and clear it with them then pick it up and go.
the key to this is who has the bill of laiden because that is the proof that the item you have shipped is yours, who ever has it has the right to the property.
you can have the bill of laiden sent with the cargo and the port manager will contact you when it arrives.
beware of frieght forwarders!!!!!!! if they have the bill of laiden, then the cargo is theirs and they can and will hold it to ransom!!!!!! they may tell you the cost to release it but when you arrive they can charge you anything they like in cash no checks no credit cars no money orders just cash or you can't have it, simple as that.
if you live away from the coast and rent a container then you can have it shipped to your door, this is not as expencive as you might think, if the container is opened at the port, be it a whole container or part, then there is a standard charge to empty it, wether it is one car or full of ping pong balls, if you have it sent to your house then you do not have to pay this part of the fees but you must aggree to this befor it leaves England and demand that the bill of laiden is sent to you at your home address where it will be delivered.
be prepared to be ripped off, freight forwarding charges will probably equal or be more than the actual cost of shipping if you don't watch out!!!!!
i see you stand like greyhounds in the slips straining upon the start, the games afoot, follow your spirit.
