Sedans are starting to gain popularity again, and rightfully so. This is a really practical style of vehicle that packs a lot of punch into a compact design. You're not going to get much more cargo space from any other kind of vehicle.
If you have a vehicle that has a third row in it, the hatchback can actually provide another entry and exit point to get in and out of. Not to mention, folding down the second and third rows provide you with even more access and space.
The compact exterior makes it easy to maneuver your hatchback around tight corners and in and out of small parking spaces.
