Two adults will fit comfortably enough in the back of the C4 Cactus (three will be a squeeze). The front seats have recessed backs, too, improving knee room. The optional panoramic glass roof (standard on Flair models) cuts some head room, though, so it’s best not to specify this if you plan to ferry around lanky teenagers.
Rear-seat passengers benefit from standard-fit headrests, large door bins and front seatback pockets. There’s a small armrest integrated into each door. It’s also worth noting that the rear windows pop open rather than lower; some passengers, such as children, might not like this. At least it’s quite easy to get in and out of the rear of the car.
