I may or may not have mentioned here that I bought a pair of Yamaha C3 scooters a few weeks ago. 2007 models with 3-4000 miles on them.

These scoots appealed to me because they're 4-stroke (quiet and more reliable over the long-term than a 2-stroke), water-cooled, and fuel-injected. Should be super-reliable and simple to maintain. Yamaha claims 115 mpg. There are no EPA ratings for motorcycles, so we'll have to take their word for it.

Anyway, I filled both scooters up a couple weeks ago, and now that my son finally got his driver's license, one of them hit E tonight.

Gallons: 1.011
Miles: 94.8
MPG: 93.77

3x the mpg of most cars, and at least twice as fun to get around on. Not fast, but entertaining if you have roads that are favorable to cruising at 35-40 mph.
