We just picked up a civic sedan about 6 months ago. I did a lot of research since getting good gas mileage and reliability was our goal for my wife's daily commute. It boiled down to the Mazda 3 or the Honda Civic. We typically get around 38 MPG from it. It doesn't have as much power as the mazda, but it did cost a bit less as well. The other option is the Civic hybrid which gets ~50 MPG, but I didn't test drive it. Both the Mazda and our Civic are fun to drive, not nearly as much as the Jeep though!!
Also, a note on the VW. We traded a 96 golf in for the civic. The reason, shot transmission. If you do get a VW (and we loved ours) do not get an auto. They are engineered to only last ~80,000 miles, which is exactly when ours went (86,000). Audi uses the same auto, so the same thing for them, as well as some Porsche models. You cannot repair them, they are sealed and a replacement will run you ~$3500-3800 with labor. Hence, the trade in. Ours was going but not gone and my friend who is a service manager at VW Los Angeles told me to trade it in "They won't test drive it.". And when we did trade in, they didn't test drive it. We got away with one there.
