About CarCast
Every used car dealer knows the feeling: you buy a truck at auction on Tuesday, and by Friday the market has shifted. The data you had was already stale when you made the decision.
CarCast was built to solve that problem. We use a proprietary AI forecasting engine — the same class of AI that powers weather forecasting and financial prediction — to generate 30 and 60-day price forecasts for 1138 used vehicle segments in the US.
Every competitor in this space — vAuto, Black Book, KBB — tells you where prices are. CarCast tells you where prices are going. That's the difference between reacting and planning.
How it works
We ingest real dealer listing data daily, aggregate it into weekly price signals for each segment, and feed 52+ weeks of history into our forecasting model. The model outputs probabilistic forecasts with P10/P50/P90 confidence bands — so you don't just get a single number, you get a range.
From that range, we derive a trend classification — Rising, Stable, or Softening. If the P50 forecast shows prices rising more than 1.5% over 30 days, the segment is classified as Rising. Declining more than 1.5% is Softening. Everything in between is Stable. These classifications are informational analytics, not financial advice or a recommendation to purchase any vehicle.
Who we serve
Our primary audience is the ~53,000 independent used car dealers in the US, along with auto wholesalers, fleet managers, and car flippers. Anyone who needs to make buying or selling decisions on used vehicles and wants data — not gut feel — driving those decisions.
Our commitment
We believe in transparent, honest forecasting. Our models aren't always right — no forecast is. But we show our confidence intervals, we publish our backtesting results, and we let the data speak. No hype. No black boxes. Just numbers.
Frequently asked questions
What is CarCast?
CarCast is a forward-looking forecasting service for the US used-car market. We publish weekly 60-day median price forecasts with confidence bands for hundreds of year/make/model/trim segments, alongside Manheim wholesale and BLS retail benchmarks.
Who is CarCast for?
Independent used-car dealers, car flippers, and auction wholesalers. Anyone whose decisions depend on where used-car prices are heading in the next 60 days.
Where does CarCast get its data?
We aggregate real dealer listings via MarketCheck, the monthly Manheim Used Vehicle Value Index (MUVVI) from Cox Automotive, BLS used-car CPI, and regional CPI series. Forecasts are produced by our proprietary AI model and refreshed every Sunday.
How is CarCast different from MMR, KBB, or Edmunds?
Those services tell you what a vehicle is worth today based on past transactions. CarCast tells you where the segment's price is most likely heading over the next 60 days. They are backward-looking valuations; we are a forward-looking forecast.
Is CarCast accurate?
Our backtested mean absolute error is 3–5% across tracked segments for the 60-day median forecast. Every forecast also publishes P10/P50/P90 confidence bands so users can size decisions to the uncertainty, not just the point estimate.
