I’m not sure your location, but I highly advise spending the extra money on AWD. If you have hills plus rain or snow, it’s the difference between peeling out from a stop and just going.

My first Sienna was FWD. We live on the side of a hill - steep enough that a family pass time is watching cars struggle in the winter. Had to park at the bottom several times with the FWD. Never had a problem with the AWDs.
