We had a Chrysler Grand Voyager in England for the last 4 years. I must say I did love it (they are more common than here I think) for the fact that it was so roomy. It was like a bus and I could literally walk up and down in the car. It was comfy, great to drive and easy to park despite the size. Great for having lots of kids and for fitting car seats as there is room for all. Also being American there are places to stash food and drinks holders everywhere. Loads of extra hidden storage too...The only down side I would tell you about is that it was REALLY heavy on fuel. Petrol is cheaper here, but in comparison to other MPVs I have to say it's probably one of the juiciest. I guess it depends how much you'll drive it and where. Longer distances were better than short, stop/start journeys like the school run. Still one of my favourite cars though! Over here we have a 7 seater Ford Territory which is definitely better on petrol consumption and still has the room inside, but it isn't set-up the same way to allow you to walk around inside.
Good luck with it!
