Until things stabilize I think getting out of vehicles at end of lease is going to be a real challenge. Both dealerships and CarMax/Carvana type places should either be giving terrible offers or just not buying cars. Right now preserving cash on hand is way more important than possibly foregoing a good used car you could make a few grand on.
Purely anecdotal, but the offer on my Accord today from Carvana was 4.5k lower than it was last month.
