Trunk comparison: Peugeot 5008 vs VW Caddy Wagon

Key Differences (highlighted)
With the seats folded down, the Peugeot 5008 offers significantly more cargo length: +28.3 in (+62%) compared to the VW Caddy Wagon.
However, with all seats upright, the Caddy clearly beats the Peugeot: +28.7 in (+215%) additional cargo length. The trunk opening of the Caddy is +13.4 in (+43%) higher than that of the 5008, which makes loading tall items easier.
Formally, the depth from the loading edge to the trunk floor is +0.4 in (100%) greater in the Caddy — but absolutely only 0.4 in, making it practically negligible. The loading edge of the Peugeot sits +4.7 in (+21%) higher above the road than the Caddy.
Implications for Usability
For long, flat loads with folded seats (e.g., furniture, long items, camping gear), the Peugeot 5008 is better suited due to the significantly greater length with folded seats.
On the other hand, if you regularly need to transport with full seating (passengers plus luggage or work materials), the VW Caddy Wagon is more practical: it offers significantly more cargo volume with seats upright and, thanks to the higher trunk opening, better space for tall items.
The higher loading edge of the Peugeot (+4.7 in) makes lifting heavy loads into the vehicle more strenuous; the Caddy is more ergonomic here and better suited for frequent loading and unloading.
The significantly higher opening of the Caddy (+13.4 in) facilitates loading bulky or tall parts and is advantageous for commercial use or transporting bulky goods.
Width differences are minimal (opening the same, interior width only ±2%); they hardly affect practical use.
Overall: Peugeot 5008 = advantage in maximum cargo length with folded seats; VW Caddy Wagon = advantage in flexible, tall/upright usable cargo area, easier loading and unloading, and better suitability for commercial use.
