This summer dealers have regularly been offering more than the traditional trade values. 1-2 year old used cars are even selling above MSRP when the vehicle was new.
This is due to the new car supply shortage which is one of the reasons used car pricing is (temporarily) cranked up. Agree worth is based on actual sell price vs. listings and valuation can't solely be based on listings. The challenge is right now many vehicles are selling at list price or above (but starting to cool off in the last few weeks).
In the past few months dealers have been making record revenue and profits in this sellers market by holding firm on asking price and negotiating less especially when they have added online purchase tools to their websites that use a one price model (eg you can't negotiate).
Our valuations are a work in progress but they already do leverage several variables tied to the overall market & supply so when used car prices normalize our valuations will adjust accordingly (and to your point lots of people who bought this summer could be underwater on their used cars a few years down the road).
