We have a Honda crv you wouldn't get 3 seats across the back. I can just get between my boys seats if I have too for short journeys. They are in a maxi rider & a booster.
They are also not too good on the fuel. For our next car I want a Mazda lol
Good luck a friend has just gone through choosing a new car & it took them few months to find the right one. Ours was bought in haste as I couldn't drive the manual anymore when I was pg with DS1.
