Google is offering me 413 euros for my old pixel 6 pro, if I buy a pixel 10 pro for 1099 euros.

Is it worth the money? I mean 413 euros is much more than I would get on ebay, I'd only get like 200 there at most. But I will still end up paying around 700 euros just to upgrade from pixel 6 pro to 10 pro.
I'm on the fence
