Hey - although I've got a Nexus500 I must give the Vespa 250GT a plug, got one tonight as a loaner (Nexus in Service) and had such a ball of fun on the way home, it's really an impressive ride!!
In my brief 45km road test I found it to be more than comfy; switches/controls most easy to operate, mirrors you can really see out of too!; power - enough to get out in front at any lights I managed to squeeze up to (with the odd exception of a "P" plater with a GTR Nissan LOL ) oh - and nice & quiet with a nice note; brilliant headlights; roomy, although no doubt not as much as say a Burgman or similar, but, heaps under seat and in the front glovebox. Fuel gauge didn't seem to move, had half tank to start, still on half tank (I hope it works LOL).
But - a very nice scooter, I can now see why so many people love them, like I now do..
