We have a '07 Yaris. We love it, but it is so tiny. DH actually said, "next car we get should be a minivan." I don't know about that with the gas mileage, but I think it may be something to consider, especially now that we have two dogs.

SIL just got a minivan. It's so sad, though, that she had to go that route because they got rid of HER car. Why? Her hubby said "I refuse to drive a blue car." *Rolls eyes.*

But with a big dog and a kid, a minivan is the way to go. Better than an SUV.
