I feel it for you. I had a 2002 sienna which I sold in 2017. Very little maintenance. Only oil change. I have a 2008 Sienna with 300K km. Very little maintenance over the years. Still use it daily. No rust. Had a 2012 Sienna AWD. 290K km. That one had a faulty transmission. Cost me 5K to rebuild. Son drove over an ice boulder on the road this January. tore a hole in the oil pan and seized the engine. Need to replace it and only looking for v6 3L used.
