Overseas buyers are welcome and can deliver to Houston for a couple hundred and can haul 3 so something else you want package deal it up. I go thru horizon auto shipping for overseas shipping. They can handle anything on the shipping aspect. Currently $850 to south Hampton UK or $850 Rotterdam so from my place to Houston port then to you at the locations above is around $1100 each bus.
