Data source
Sold prices come from public auction results (for example Bring a Trailer, Cars & Bids, PCARMARKET, Collecting Cars, Hagerty Marketplace and others) compiled from Old Cars Data auction records. Each row on the site links to the original listing so you can check it.
What's included
- Only auctions that sold. Unsold high bids and dealer asking prices are left out.
- Cars only. Parts, wheels, seats, engines, memorabilia, replicas and incomplete cars (rolling chassis) are excluded (245 lots in the current pull, including unsold or undated ones).
- Restomods and tuner builds (for example Singer, RUF, Gunther Werks, Kaege, Emory, Brabus and "backdate" conversions) are excluded. They're priced as custom commissions, often 5–10× the car they started from, and would distort the model's figures.
- Each sale is assigned to a model page using the provider's model field, the listing's model label and model year. A generation label that contradicts the model year (for example a 1983 911 "with 964 styling", or a 2022 car labeled 991) is resolved by model year, and a 1950s 356 "Carrera GT" is not counted as the 2004–2007 Carrera GT.
- Prices are hammer or sold prices as reported by the provider. Buyer's-premium treatment can differ between auction houses.
Statistics
- Median, low, high are shown when a model has at least 3 U.S.-dollar sales in the sample.
- Fair price range is the 25th–75th percentile of USD sold prices, shown only when there are at least 5 USD sales.
- Sales in other currencies (GBP, EUR, AUD) are shown in their original currency and excluded from USD statistics. We don't convert currencies.
- The snapshot window is the last 12 months of sales in our sample. If a model has fewer than 5 USD sales in that window, we use every sale in the sample and say so on the page.
- GT/RS split. When GT-department track and limited models (GT3, GT4, RS, Spyder RS and similar) make up at least 20% of a model's recent USD sales, the page also shows the median with and without them, because they sell at a large premium.
- Value by trim splits the window by trim as read from the listing title, shown only for trims with at least 5 USD sales.
- Our sample keeps every sold auction we have pulled, and weekly refreshes add to it. Most models go back at least 12 months; a few rarely-traded models have long histories but only a handful of sales per month.
- The 12-month market trend panel shows Old Cars Data's own statistics (monthly average price, volume, sell-through). They're unfiltered, so they can include parts lots and outliers.
- Where there aren't enough sales, the page says so. We never estimate, model or invent prices.
How the market signal works
Each model page shows a Buy / Hold / Sell reading: a rough answer to "is now a good time to buy or sell this model?" based only on the sold USD auctions in our sample.
- Windows. We compare the last 3 months (91 days up to the model's latest data date) with the 3 months before that, and fit a 12-month trend.
- Minimum data. A rating needs at least 15 USD sales in each 3-month window, and our sample has to reach back over at least half of the earlier window. Otherwise the page says "Not enough recent sales for a signal". Rare models (for example the Carrera GT) often don't reach that bar.
- Venues. Only always-on online auction platforms (Bring a Trailer, Cars & Bids, PCARMARKET, Collecting Cars and similar) feed the signal. Live auction houses hold big sales on a few dates, such as Monterey Car Week in August, and sell a pricier mix of cars, which would otherwise show up as a fake seasonal "price rise". Those sales still appear in the price tables.
- Mix adjustment. A median can jump just because more Turbos or newer cars happened to sell. We take out each sale's trim (pooled median by trim) and model-year effect (a robust Theil-Sen fit), then compare the median of what's left between the two windows. The raw median change is shown too.
- Noise check. We resample each window 2,000 times to get an 80% range for the change. If that range includes zero, we treat the move as noise.
- Trend. A robust Theil-Sen slope of the mix-adjusted prices against sale date over the last 12 months, shown as % per year.
- Sell (sellers' market): mix-adjusted median up at least 8%, the 80% range above zero, the raw median also up, and a 12-month trend that is flat or rising.
- Buy (buyers' market): the same in reverse, down at least 8% with the trend flat or falling.
- Hold: everything else: a move under 8%, a move within noise, or signals that disagree.
- Volume (sales counted by the data provider) is shown for context only. Our own sample is capped, so its counts can't drive the rating.
It's a summary of recent auction results, not a forecast, an appraisal or financial advice. Condition, history and options matter more for any single car.
Limits
This is a sample of public auction results, not all U.S. sales. Private-party, dealer and trade-in transactions aren't included. Auction cars are often better presented than average, so they may skew high for some models. A single car's value depends on condition, mileage, history, trim and options. Use these figures as a starting point, not as an appraisal or a lending or insurance valuation.
The current sample holds 6486 sold cars and refreshes weekly.
