I'd love a highly fuel efficient 4 door with a 6 foot bed. I don't need it to haul much, or have massive ground clearance. I just want to be able to put things in the bed sometimes and get good mileage all the time.
The alternative has been a solid mid size wagon, but you lose the ability to stack things up in the back.
I've tried to seriously consider the mini transit van option, but the mileage isn't quite there and the backseats eat up the cargo space.
