I have three Carseats in my Kia sorento platinum. Love that it has two extra seats in the boot that pop up if needed...and we have used them a lot for visiting family members. They come standard. Love that it's a diesel too... I feel like I hardly ever visit a servo now!
Some pps have mentioned that they see no need for an SUV, but in my case that is one thing I WISH people had told me was a necessity. I had a sedan and found it very difficult lifting my baby/child into the car and having to lean in killed my back. It was horrible when pregnant with my second and third kids. Now I have an SUV it's so much easier to get them in the car- I have the side steps to help my oldest climb in and she loves it.
I also love being up high from a driving perspective.
My picks would be the diesel territory, Mazda cx9 and f course my Kia sorento!!! I chose it over the others because of price comparison on the diesel models and it has much higher specs than the others, I love a bit of luxury
If you can afford it, leather seats are a great option for kids- wipe clean
