Look, I couldn't find a good picture of a bunch of Ikea flat-pack boxes inside a hatchback. Consider the pic I used "representative," not literal.

The point I was trying to make is that that volume of stuff would easily fit in, for example, a Hyundai Accent subcompact hatchback with the rear seats folded down. (I know this for a fact because I used to own one.)

The only reason it needs to be on the roof of an old air-cooled Beetle is that the engine is in the back.
