I don't necessarily think you have to get a hybrid, but if you can afford an SUV or a truck, you could have bought a mid-size car, or even spent less and got more gas mileage (Yaris or some ****). All trucks and SUVs cost more than a gas efficient car, not a hybrid. New trucks and SUVs cost probably the same as a hybrid. If it's an old beater, and that's all you got, you could probably trade it for an old beater car. My only argument is if you bought a truck, at some point you did not care about gas mileage, and in my belief, you forfeit your right to *****. You made your bed, now lay in it.
And as for the work truck, what's that line everybody here likes to throw around? You don't like it get a better job?
