My parents have a 2013 Sienna, before the last interior refresh, and the only feature I'd like to see is the reclining middle seats. Now those are nice seats, but no way it would work with the Sto-and-Go. And the adjustable headlights is pretty nice as well.
All the seats in my Touring L recline. The middle seats have a lever on the side. The back seats have a strap near the van side (since they aren't power). Your seats probably recline also.
