Modern Vespa

Gday all.
I'm curious as to what economy everyone is getting out of their scoots in the real world, none of this "advertised" stuff that means nothing.
And, since I live in an area where just starting up your scoot means your sitting on it for the next 1.5hrs until you reach the nearest next fuel stop, I'm most interested in highway economy.
And, also since I'm asking , I would like to hear from all those owners that have measured their economy on highways through rolling hills at a steady 65 - 70mph, whatever scoot they have now, doesn't have to be the "italian supermodel".
Waiting patiently.......sort of!

I ride my GTS 300 daily in the car pool lane on the freeway, which means I am pretty much WOT all the way there. My round trip is around 62 miles. I get about 128 miles per tank, give or take, at this speed. My mpg (as you can see from my Fuelly bar) is approx 60-62 mpg.
When I am not on the freeway, I can get up to 70 mpg if I am at or under 45 mph.
