Yes, I find that with my Prius, even under "bad" conditions I still get higher gas mileage than other vehicles and it does everything I need it to do. I can easily fit 2 bikes inside, and have hauled lots of other stuff in it too. I didn't suggest it here because I didn't think it would work in the OP's case.

I had to drive a Matix for a few weeks over the summer and it killed me to have to fill the tank so much more often than my car. I also preferred the way my car drives (quieter, etc.).
