Foamit Up

I bought the C-Max for my wife to drive to work 20 miles with speed limit of 45 half way. We had a mini van before, but kids are gone now. I really wanted the 47 mpg as gas is high in Maine. Asked the dealer three times if they really got 47. His answer was that this car has been totally tested overseas and yes it got 47 some times more. I liked the room it had for a 6 ft 4 person. So we got it even though i thought it was a little expensive but if it got 47mpg it would be worth it. Well we have 5500 miles on it and have never seen over 38 mpg. So i am not a happy camper, but not much you can do now. I can not even take it out of the garage ( 30 ft on level ground) with out the engine starting up. I am not impressed.
