Updating this thread as I sold my Equinox today.
Peak pricing was around Oct for 26,600 from Carvana and has been on a slow decline since then. In July 2021, Carvana was offering about 24k.
Sold today at my local GM dealership for 24k. In my area, most GM dealers offered 19-22 saying that they would rather send the car to auction. One dealership would not even make an offer since they had too many cars.
There are no issues selling GMF leases across state lines. My car was tagged/registered to CA but sold in Detroit metro.
Check was issued same day and I was out in 30 mins. Dealership cut me a check and then grounded the vehicle.
