Apparently the newer Kia's are much better than the older ones.

I have a ford Territory and It is lovely to drive. It has 7 seats. Can your eldest do up their own seatbelt cos it would be a pain to try and reach them to help in the back. It is not that great on fuel. The new model (not yet released, is supposed to be much better and also has gas and diesel options). The boot space with the back row of seats up is not amazing. Lot's of mums with 4 kids suggest that they opt for an umbrella stroller cos of the space saving.
