zafira are good, but a smaller mpv. if you really want space look to the bigger varieties.
i had a sharan, that at the time was built in the same factory as the galaxy and alhambra. very nice car to drive but had loads of problems, the biggest being air con that i threw over 1k at but still did’nt work for more than a few months.
then bought a 4 yr old kia sedona. you get a lot of car for your cash, the slide doors are a godsend, but the build quality is appalling and its a pig to drive. also had loads of probs, some major (air con), but as it was from a kia dealer had warranty. i don’t like kia at all.
not sure what i’ll buy next, they all seem to cause problems. that aside, i look for completely removable rear seats, captain seats, fold down tables for the kids, arm rests and most imp of all cup holders.
