It does really good on gas and it has lots of room for a medium to large sized family with the optional third row seating.
I love my car. It has enough room for my family plus plenty of room in the back for groceries, outdoor equipment, etc. The only thing I don't like about it is I've been having problems with my gas tank/sensor/gauge. If it goes under half a tank I have to get gas immediately otherwise the gauge will drop to empty, even though there is still gas in it, and my car will act like it's out of gas and shut off. If I put a couple of gallons in it it will raise back up to over half a tank and register correctly.
