Just tried to buy one of these things to go on a hypermiling odyssey across the US. It's a 49-state EPA certified 250cc twin cylinder with a 72 mpg EPA rating and manufacturer's VNE of 50 mph. Recommended cruise speed of 45 mph, proven top speed of 60. I think these 250s are rare because you can't get them anymore. Same story as the Smart Car, they'll keep bumping up the engine size for more power.
A neat thing about the transmission is that you can go to neutral from high gear!

I plan to modify it extensively before the trip. Suggestions are welcome.
My thoughts right now.
1) aerodynamic skirt on front wheel, side skirts on rear
2) replace driver's seat with a comfortable one
3) toss the passenger seat and rear seat
4) install a comfortable passenger seat over the right rear wheel that folds down for sleeping
5) 12" scooter tires all around with larger o.d. than stock
6) bigger battery
7) solar charging roof cover
8) pull the rear doors and cover openings with aluminum sheeting
9) turbocharger! (for mileage)
10) lose the roofrack
Craig V. says to put a 4-foot tail on it! That's a great idea.
If you want one, I found a new one here for $7400 (pictured)
