I have a Toyota Matrix. It's a hatchback with a back seat that folds down into a flat bed. It's big enough for me to fit a bike without removing the wheels. Works for appliances and furniture as well.
The worst part of buying stuff on the Wii U shop is that you can't store it on a tiny SD card. You have to plug in a full external hard drive. This seems like a pretty obvious thing for them to fix in this iteration.
