i'll give you 10k for it
but seriously, driving habbits are what effect someone's gas mileage. I average 34mpg driving 10 miles highway at 80-90 then the next 10 in traffic. stop and go, stop and go. Last week my wife borrowed the car to see how much better i really got than her Pilot. No guessing for me what the difference would be. But she took the same route to get to her work as i do, then add another 15 miles one way stop and go for her, yet she averaged 37mpg. Go figure
