Look up a vehicle forecast

Real listings, not surveys.

Forecasts are trained on weekly snapshots of real dealer listings via MarketCheck.

Bands, not point estimates.

Each forecast shows a 10th–90th percentile range so you can size the risk.

Looks forward.

Most pricing tools tell you yesterday's prices. CarCast projects where the market is heading over the next 30–60 days.

Frequently asked questions

How are CarCast's forecasts produced?

We train a proprietary AI forecasting model on weekly time-series of real dealer listing prices (MarketCheck), wholesale auction signals (Manheim MUVVI), and macroeconomic context (BLS CPI, regional CPI). Forecasts refresh every Sunday and project the next 60 days as a median (P50) with P10/P50/P90 confidence bands.

What do P10, P50, and P90 mean?

They are confidence percentiles. P50 is our best single estimate (the median). P10 is the level we expect prices to fall below only 10% of the time; P90 is the level we expect them to exceed only 10% of the time. The P10–P90 band shows realistic best/worst-case range.

How often are forecasts updated?

Every Sunday morning, US Eastern time. New listing prices land throughout the week, the model retrains over the weekend, and refreshed forecasts publish before Monday open.

Can I trust a 60-day forecast for a fast-moving segment?

We publish mean absolute percentage error, not a blanket accuracy percentage. The current mean absolute percentage error, the number of forecasts scored, and the horizons included are on /accuracy. A forecast counts only after its horizon has elapsed, against the later MarketCheck listing median for that segment. That figure is a live outcome, not a historical model backtest, and it is not a guarantee for any one vehicle. We do not publish a directional hit rate. Wider P10/P90 bands on a vehicle page mean more uncertainty.
