Looking to replace my 04 Sienna with a used one from the 2012-13 range. Any significant advantages getting a 2013 over 2012. I looked back at reviews and doesn't seem to be much difference other than the 6 cylinder being standard in 2013. I would only buy a 6 cylinder if buying a 2012 and at least a LE like my 04. Also looking at 2014 but the ratings don't seem as high for that year.
