If you want something that can be serviced anywhere in the world .. it has to be fixable with a hammer, not a computer. Other than that .. you want a local dealer who is prepared to send you parts anywhere in the world .. arrange that before you leave. Do realise that shipping the parts is only one part of the problem, you need to be able to identify the parts you need, be able to fit them, pay the import duties to the place your in and wait for the parts to arrive .. delays in shipping can be long particularly in the receiving country.

-------------------------
The world is a large place. Shipping your vehicle will be required to get to various places .. the size of the vehicle should be small .. if possible to fit inside a container .. even a 'high' container... with some clearance ... shipping a standard container is much easier and less expensive than some odd shape vehicle...

Door entry dimensions - standard 2.33 width 2.28 height ... HIGH 2.35 width 2.58 height

length - internal standard 5.09 ... long (and HIGH) 12.01 (all in metres)

Ideally you would like to loose
1.3 metre in length (say 1.2 minimum)
1 metre in height (say 0.9 minimum) ... that would save you a lot in shipping costs .. assuming you will be shipping.

Do plan a way of getting out when it is inside the container!
