Trunk comparison: Seat Ibiza vs VW Golf Wagon (Mk5)

Key Differences
The VW Golf 5 offers significantly more cargo length: with the seats folded down, the Golf's trunk is
longer, and with the first row upright, even
longer. The opening of the Golf is also wider: the width of the trunk opening is
greater on the Golf. For the Seat Ibiza, the opening height and the depth between the loading edge and trunk floor are larger: the height of the trunk opening on the Ibiza is
above that of the Golf, and the depth (loading edge → trunk floor) is
greater on the Ibiza. Smaller differences (loading edge height above road +8% and narrowest trunk width +1%) are negligible.
Impact on Usability
The longer interior dimensions and the wider opening of the Golf make it more practical for long or wide cargo (e.g., slats, furniture parts, skis): longer items fit more easily, and the larger opening facilitates loading and unloading bulky parts. Because the Golf provides significantly more cargo length both with folded seats and with the seat row upright, it is overall more flexible for transports where length matters. The Ibiza scores differently: the higher opening height allows somewhat more vertical space when directly placing tall items, and the significantly greater depth between the loading edge and trunk floor means more space "downwards" — useful for durable, stackable, or bulky cargo that can sit deeper in the trunk floor. However, greater depth combined with a higher loading edge can make lifting heavy items during loading more difficult. Conclusion: For long and wide transports, the VW Golf 5 is the better choice. For transports where vertical space in the trunk or a deeper cargo area is important, the Seat Ibiza is advantageous — though potentially with less comfortable lifting for heavy loads.
