 Just got it.  250 miles home on the highway at 31.5 mpg.  Speeds between 45-75.  Not much city driving yet.  Short trips get poor mpg maybe because the engine isn't warm or the battery charged.  My 15 mile commute averaged about 24.5 mpg city.  Can't comment on reliability or maintenance yet.  hopefully won't need to.  I do love watching the speed climb while the rpms hover.
