I'm only on my first tank but I averaged 39 MPG and this is 70% city driving. I work close to home so I'm only on side streets most of the week. A few nights and this past weekend I've taken longer rides with highway driving.
I've also been using all modes, sport quite often so I'm sure I'll get better mpg once I cool it on sport mode.
Really though, it rides nothing like a civic. The handling is what sold me.
Look of cars are always subjective so I don't mind when people say it looks ugly on here, though people are so excited in person.
But when it comes to the actual ride of the car, I'm really enthusiastic about it. The car basically changes with a touch of a button. I can drive slow like a grandma in eco mode - but it still rides really smooth... put it in sport mode and zip around corners or normal mode and drive, well, normal.
I suppose there's other cars like the GTI that have similar results, but for what the CRZ has to offer and price, I thought it was a good lease for me. The speakers are really good better than the bose system in my MS3, it has a subwoofer, touchscreen nav is useful (though outdated in graphics) but definitely better than iPhone Maps lol, bluetooth works well with my iphone4, talk to the car is cool - I don't know what that's called, Multi-Information Display for things like oil changes, tire rotation, eco score, MPG per start up, etc. are nice touches.
I think it has just enough stuff to tide me over for 3 years.
