Trunk comparison: Peugeot 3008 vs VW Caddy Wagon

Key Differences (>10%)
The Peugeot 3008 offers significantly more cargo length with the seats folded down: +20.1 in / +44%, giving it a clear advantage for especially long items.
At the same time, the 3008 has a greater depth between the loading edge and trunk floor (+3.5 in / +450%) and a significantly higher loading edge above the road (+9.1 in / +40%), which makes lifting heavy loads more difficult but, combined with the longer cargo area, creates more usable volume for flat, long loads.
The VW Caddy Wagon, on the other hand, scores with a significantly higher trunk opening (+14.2 in / +46%) as well as larger interior and opening widths (Interior width +4.7 in / +12%, Opening width +4.3 in / +11%).
This makes the Caddy more practical for loading and unloading wide, tall, or bulky items and facilitates loading through better accessibility.
What impact does this have on usability?
For long, flat, or extensive loads (e.g., slats, long furniture parts, bulky boards), the Peugeot 3008 is the better choice due to the longer cargo area with folded seats.
The greater depth of the cargo space increases usable volume lengthwise; however, the +9.1 in higher loading edge is a disadvantage when lifting heavy items: loading requires more effort.
The VW Caddy Wagon is better suited for bulky, wide, or tall cargo (e.g., boxes, furniture pieces, equipment) because the opening is significantly higher and wider and the interior offers more space at the narrowest point.
The lower loading edge makes handling heavy items easier and more back-friendly. Disadvantages arise when transporting very long items: here the Caddy lacks the length that the 3008 offers when the seats are folded down.
Additional notes
A smaller difference in favor of the Caddy is the longer trunk length with the first row of seats upright (+3.1 in / 8%); this value is below the 10% threshold and is less decisive in practice than the contrasts described above.
Conclusion: Peugeot 3008 = better for long loads and more usable cargo space lengthwise; VW Caddy Wagon = better access, more width/height, and easier handling of bulky or heavy items.
