We bought a 2006 FEH 4wd about a year ago, mainly for the wife (she didn't necessarily want a hybrid, but she wanted a small SUV to haul around 2 kids and I really wanted a hybrid in the family, so voila). I "settled" for a mercedes

for my work commute.
Well after about a year, I realized that I liked the FEH more than my benz. Every weekend I would drive her FEH, and she would drive my car (assuming she didn't have to bring kids with her)! So I sold my benz, got her a new small-ish SUV (the acura rdx - tried to talk her into another FEH but she didn't want two of the same car, and the highlander hybrid or lexus 400h were way more money than we wanted to spend and didn't get much better mileage than the rdx), and I took over the FEH fulltime!
She had been getting about 26-27 mpg per tank in the FEH, but my first tank (thanks to what I have read on these boards) was 31 MPG!!! weeeee!
