Scooter-wise I'd recommend the Vespa P200 if you can find one. They are bullet proof, parts are pretty common all over the world. If you want something with a little larger wheel, I'd say an older Honda C70 Passport or the newer Sym Symba. Pretty much the came thing. Again a bullet proof design and common parts all over the world.
The Vespa would have a bit more maneuverability due to the smaller wheels. The Honda would have a probably have a smoother ride due to the larger wheels. I think with either bike you can't go wrong.
