Two factors that I'm aware of:

-- Early in the pandemic, travel was way down. Rental car companies unloaded a lot of their fleet that were sitting idle. Now that demand is back up, they are back on the market for vehicles.

-- Semiconductor shortages: automobile manufacturers cut their orders in early 2020 anticipating a decline in demand. That decline never happened, so they're now now able to obtain sufficient chips for new vehicle manufacturing. Thus a decline in new car availability that might push some car-buyers onto the secondary market.
