The Sentra's 13.1-cubic-foot trunk is similar in size to its main competitors, but it offers greater cargo versatility thanks to a large opening when you fold the backseat. It takes an extra step to fold the seats — you have to flip forward the seat cushion first — but once the backrest is down the opening's extra size is clearly evident. This is an uncommon seat-folding design — many compact cars simply have backrests that fold down — and it may mean you'll have to move the front seats forward a little so the cushions can flip forward far enough for the backrests to clear them on the way down. The rear head restraints don't have to be removed before folding the seats; they simply flip forward. Still, it's an awful lot of work to fold the second row. You can fold the seatbacks without flipping the bottom cushions forward, but if you do you're left with highly angled backrests that aren't flat with the cargo floor.
