I had 1 and 2 in my mitsi colt and used this quite a lot when we went on holiday especially when we had suit cases in the back and we had 2 passingers in as well.The mitsi also had sliding seats as well this was useful, but with the rear leg room being limited as it is I didn't think there would be much benefit from this in a mini.I think number 3 because the only place in the car to store them is behind the front seats or length ways if you have the seats folded or as I do take them out and leave them in the garage.as for the wipers mine don't work when i select reverse.
