We have a Peugeot 307SW. It's not got the bulk of some of the mpv's but I have 2 extra seats in the garage and they can be put in and rearranged. Most of the time it's just a 'normal' car but if you want it to be six or seven seats you can change it in minutes. You can even remove all the back seats to give a large rear area. It's not too high and not too long. For cars which don't obviously look like people carriers the Honda FRV is a six seater, the Toyota Corolla verso is a 7 seater, Fiat Multipla is a 6 seater. We've got 2 kids and having the option of extra seats for grandparents/friends is great.
