What are they like inside? These are small cars, not city cars, so they should be able to comfortably carry four adults. The Skoda Fabia and Chevrolet Aveo do exactly that, with enough leg and headroom for all but the tallest of back-seat passengers. Things are cramped in the rear of the Suzuki Swift, because the sides of the car taper in, eating up headroom.The Swift also has the pokiest boot, with barely enough room for a few bags of shopping. The Fabia and Aveo offer similar amounts of space - enough for a couple of large suitcases or a pushchair. The rear seats in all three can be folded down when you need to carry bulkier items.
