Definitely the Mini Moke.
My parents had one as their only car when we were growing up. Ours had no back seats, just a couple of old blankets to cushion us from the steel deck. Mum and Dad up front, all four kids and a grumpy Bull Terrier (which once ate nearly the whole the hood) squeezed in the back.
We liked to sit on the side pods gripping the seats and grab rails, screaming for Dad to go faster round the corners with our knuckles turning white wondering if we could hold on until the next straight!
I loved it then and I'd love one again now.
