You are not going to move furniture with this on a daily basis, but if that's what you want get a truck.
Smaller car doesn't necessary mean less storage. The concern here is that the opening isn't large enough to be able to even put stuff into the car. Even a moving truck looses utility if the doors are only as large as a laptop.
I could see this rear trunk possibly being problem for some people going to buy wholesale items at Costco/ Sam's Club let alone furniture.
At least the 3' still has the frunk. But we could see the trunk being significantly smaller than we we're used to seeing given sacrifices for interior leg room.
