This is a hybrid forum, but what are you actually driving?
I cannot afford a hybrid right now (or any new car). Our family vehicle is a 2003 Ford Escape v6, not the best for gas mileage (21-23 mpg average) but it gets the kids around. For my daily commute I am driving a 1992 Mercury Tracer that still gets 27 mpg highway (recently bought to replace a truck that got 19 mpg).
