It might be a location thing, but when I was shopping in the latter part of 2025, the ES350 was typically more expensive, with more miles, than a comparable year Avalon. Trust me, I was trying to find one that would fit the bill, but, at least in the Midwest, I was having a hard time finding anything for a decent price with low miles on it. There was typically a $3K-$5K difference in cost in my experience. I think either way though, you can't go wrong.
