I had the Alhambra before the Peugeot Rifter LWB and as the Touran is about 10% smaller than the Alhambra/Sharan then I can tell you it is quite a lot bigger than the Touran when it comes to interior and boot space, even the 2 3rd row seats can fit 2 adults in easily with loads of space and legroom/headroom and the AP’s are way less than the minibus types.
