I think you may want to add some info about your budget, whether you want to buy new or second hand, your likely usage etc, preference as to Diesel or Petrol.
I have child no. 3 on way and were looking at getting a 5 seater. Initially I was looking at scrappage as I have a scrappage car but even then basic model Renault Scenic was over €19k.
Models I was looking at were the Scenic, Citroen Picasso and Opel Meriva. I stand to be corrected but I think the Seat Altea XL has 3 separate seats too.
I'm not sure there is a 5 seater Toyota Verso. There is a 7 seater to be sure. The Fords C Max are expensive new or second hand so I wasn't considering them myself.
Ultimately we may go for a 7 seater ourselves, our mileage is low so we would likely go for a petrol Second Hand Model 2007 (we don't believe the savings on a Diesel would make up the difference on the price due to our usage).
