7. 2013 Toyota Prius VStarting price: $26,650 So what if its combined 42 miles per gallon now lag behind the 50 of the original Prius? The V's 67.3 cubic feet of cargo space is what matters during a long haul with the family, and that's way better than the original Prius' 39.6 cubic feet. In fact, it's a whole lot closer to the cargo space of compact SUVs such as Toyota's RAV4. You're getting all of that space and still getting three times the gas mileage of the family you saw at the dealership climbing into that Sequoia. Not too shabby.
