I have had an 03 Element EX & now an 07 AWD CRV. Best MPG I got out of my Element was 24MPG all highway. Last trip (all highway) in the CRV I got 34MPG, but usually, with about 80% city, 20% highway, I get 23-25MPG.
CRV seats 5, Element seats 4. CRV looks more "upscale" inside than the Element.
Biggest complaint I had about the Element was the doors. You have to open the front to get to the back.
But the element has all those seating configerations in you haul things.
CRV seemeds to be quieter, but it has that constantly shifting tranny (that I hate) when compared to my Element's.
CRV has all 4 windows that roll down, plus electric roof (if you go EX or higher). My element's back windows didn't roll down.
The Element's rear seats seem a little more comfy, but I didn't spend much time in the back of either car's seats.
Styling on both cars is very personal - some like both, some don't some like one more than the other.
EX CRVs up have radio controls on the steering wheel, my Element didn't
That's about all I can think of right now
