You may mock. But you won't find me asking questions about which adhesive I should use to hold my roman chariot of a car together.
Actually, I thought if I ever needed a 'Mummy Bus' (Unlikely, but you never know ) I'd go for an Orlando over the Zafira.
There are no more new ones, so you'd have to have a used one. If you're seriously considering one, be aware that spares are becoming harder to find. A guy on the forum had to pay a dealer £24 for a rear wiper...outrageous but no choice. No one will bother setting up the tooling to make cheaper parts, there aren't enough of them about.
I'd go for the zafira, Tigger, cheap as chips and easy to maintain. The fact that you're considering a people carrier means you're looking for something to work for you rather than something to look at. Zafira parts and repairs are readily available and hassle free is what you need.
The orlando has parts which are not in common with the zafira, like the climate control system. If something like that goes wrong, it would be really difficult to find someone to repair it.
Just an honest opinion, I don't want you to come unstuck so I can sing the praises of my car, although I do like it.
