I wouldn't want a 3 because it isn't a hatchback. Hatchbacks are just so wonderful for transporting large items and even for sleeping the occasional night!
I love my Prius for this very reason, fold the back seat down and it’s got plenty of room for moving stuff around (being mindful of the max weight the car can reasonably haul) - if it wasn’t for my semi-purist nature when camping I’d seriously consider camping in it instead of pitching a tent.
