Having recently been looking for a people carrier, here's my verdict. (And I know these might be a little out of your price range, but worth noting.
-New Zafira = Hateful thing. Couldn't get on with it at all and the 120 version wouldn't pull you out of bed in the morning.
-Kia Sedona = Very big, but very cheap, noisy, slow and the steering was so low geared even going round a shalow bend resulted in flailing of arms.
-New style Fiat Ullyse = Didn't like it. Very slow, but very funky interior. Peugeot and Citroen variants are better spec'd and infinitely more reliable though. The old style ones are apparently very good value for money. All of htem have sliding rear doors. (A real bonus if you have children that neeed help getting out of the back seats in car parks.
-Chrysler Voyager. Brilliant and with those sliding rear doors. Depending on who you speak to they're either wonderfully reliable and nothing ever goes wrong, or they're awful things that keep the AA in full time employment. Lot's of room and good spec'.
-Ford S-Max = Outstanding car. Just like a Galaxy only a bit smaller. Nippy, comfortable, drove like a car and well spec'd. No automatic option though. I'd have one in a minute.
