Our best MPV of 2012 has to be the most multi-purpose of vehicles. Above all, space and practicality are crucial: what we want is a car with plenty of room inside to act as a family ferry, but with enough permutations in its cabin and seating arrangements to cope with a variety of demands. Mind you, these demands will be financial as much as practical; an MPV also has to be affordable to buy and run, and must come with the right equipment at the right price. Given how precious its cargo will be, our best MPV of 2012 will also have to come with the latest safety equipment.
