I too have the FFH, just picked it up on Sunday and love it. Here in sunny, hot, humid FL. I've had great MPG out the gate, even when it's relying on the gas engine for power. After just 4 days, my long term avg has moved from the start of 21 mgg to 30.3. Granted my commute is 25 miles one way, with a mix of city/toll road, but I'm still getting between 38 and 41 mpg per trip. Have the 502 package, because that's what they had left, but that'll come in handy visiting the relatives in Indiana next winter. :)
