I doubt this. Normal people don't care, especially not those looking in the used market. If this were not true, I'd not have a majority of anecdotal accounts of people paying asburd sums for baseline macs brand new that might have even already been out of date.

In one case, I knew someone who "wanted something to watch movies on" and bought a 13" brand new base model macbook pro through a third party installment company. Ended up paying around $4500 CAD for a 13" laptop with 4gb of ram. She tried selling it to me for a huge discount, but even that couldn't have been worth it.

8gb version is so cheap (constantly on ~100€ discount on Amazon, 950€ right now) even if the % loss is high, total loss is low. I'm comparing it to new MBP pricing (13 inch M1 mbp seems pointless) which would be the alternative here - the cheapest m1x is 2.5x the price.

Heck it be worth keeping as a backup device. The only question is - would 8gb version work for you.

Also, I'd recommend buying it from Apple's education store for $100 off if there isn't anything cheaper. It's $200 off at Microcenter sometimes as well.
