9. Toyota Prius VMSRP: $26,650 Even the Prius V's website declares the inevitable: An icon grows up. That cute little Prius you used to rent from Zipcar ( ZIP) for weekend road trips and grocery outings back when you lived in the city has followed you out to the 'burbs and transformed into a wagon. 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 considerably larger than the original-recipe Prius' 39.6 cubic feet and is closer to that of compact SUVs such as Toyota's RAV4. No, you're probably not going to be parallel parking this one as much, but those grocery runs are getting a lot bigger now that there are more mouths to feed. Besides, it's still the most fuel efficient vehicle on this list. That has to count for something, even if it's not quite as sexy as the smaller model you remember.
