Maybe, maybe not, it's best not to try to find out until you've bought a few large items and then consider it last minute.

Getting yourself into tricky situations due to lack of planning and then making up solutions on the spot are some of the most fun moments in life. 🌞

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.
