Lease ending, looking to buy Used ID 4

I got my Manheim inspection, and no charge to turn in my 2023 model. Yay!

My questions are these –

I really want to get a 2024 or '25 pro if I can get one for no more than $26,000. There are a few (like three) in my metro area at the moment. Also a couple in Pennsylvania a couple hours away.

How much would you value a certified pre-owned (with two-year additional bumper to bumper warranty after four year factory warrantee ends)? According to VW Credit, I can save my turn-in fee if I get a CPO, but not a standard used (which I think is $695?)

I should buy before my lease ends, right, not try to extend for more 24s to return to dealerships? ($345/month)

If this is true, then maybe it’d be helpful to calculator the difference in price of a CPO vs. non-CPO and subtract out the dispo fee?

What is your reasoning?

My reasoning is that there are almost no VW ID 4s pro trim 2024 or 2025 for sale right now. I have a 2023, and they improved the battery and software for the infotainment screen in 24.
