My wife's car (the one we use 90% of the time, since she likes to drive and I don't) is an old Mazda Protege. Standard transmission, non-hybrid, etc. We get a little over 30 mpg with it city, and between 45 and 50 highway (which we don't drive very often). Our commute is just about 1 mile each way. We've owned the car since '99, and it just hit the 60k miles mark, which includes moves from Montana to Washington DC, and from DC to Texas. It's had routine maintenance and been very inexpensive to own.

I keep thinking about upgrading that to a hybrid, but the numbers don't add up quite yet. Probably will in another year or two.
