A van, economical and nimble. Automatic, that is perfect. It also has ACC cruise control, very simple to drive.  

Perfect for two, perfect for a family with two little kids. Four beds, one big at the back and one for children above the kitchen space at the front. Very comfortable for 2 people, since you can fold the front bed.

There is a possibility to put a bike rack, on the trailer hitch.
