Question from potential buyer

Hi all,

I’m contemplating a sienna for my next daily driver, but I wanna make sure I get the right year. The newest lineup advertises second row seats that “cannot” be removed (yes I know they can be, but it’s a lot of labor).

So I was curious as to what is the latest model that has flat/removable second row seats was? And what the fuel economy was on it. I currently drive a Camry that’s scoring 26 MPG, so I would prefer to stay close to that.
