A lot of the prior conversation was about model-level new sales. Totally agree on with you on used being volatile based on lack of supply. I would say even if there's a lack of supply as you know the further your perspective the more predictable used gets. But yeah 1 dealer in 1 month it's pretty challenging. As we used to, I still like the approach of using the first 72 hours of engagement data after a car goes live, the dealers prior history and the market's history to smooth out.

This approach is similar to how you can use early player stats in baseball to determine reference players with similar trajectories. The first 72 hours shows you the early career, the dealer and market history give you the comps. If you track time series engagement data you can do this. For the nerds: Career Trajectories
