MMR Help

MMR Help

The MMR is a tool that will help users find pricing on vehicles that interest them most, across all Manheim inventory. In addition to basic information, the MMR provides users with pricing projections, transactions listing, auctions listing, summary information and a variety of reports based on their selection.

The MMR can help you research vehicles quickly and easily. It can target specific vehicles nationally or by region as well as for a given year, make, model and style (trim or key options) by displaying recent transactions and summary values derived from transactions

Frequently Asked Questions

You can access MMR from the Buy and Sell tabs located on every page of

  • Enter a full VIN or just the first 10 digits.


  • In the Description fields you can choose the year, make, model and style, region
  • In the Option fields you can select region and if want it seasonal adjusted

It’s not uncommon to find differences between MMR values and guidebooks. MMR prices are based exclusively on millions of actual sales that are updated daily. The statistical programs that compute the averages are completely neutral, using universally accepted statistical techniques without editorial opinion or bias. MMR programs do not use interpolation to compensate for insufficient data. Guidebooks, which do not have access to the same amount of data as the MMR, use editorial expertise and limited market observations to arrive at prices.

The MMR makes old-fashioned mileage tables, that do not allow for differences in how a vehicle is used, obsolete. The MMR statistical programs compute a separate average mileage and per-mile depreciation factor for every vehicle in its database.

The base MMR is the average wholesale price, odometer and condition grade of recent transactions for a given year, make, model and style. It does not include vehicles that sell for values far above or below the average. such as a customized pickup that sells for $100k, so the base MMR won’t be thrown off by outlier sales.

Recent transactions are more heavily weighted. This ensures that the base MMR reflects seasonal trends and market dynamics, so that it captures today’s actual market value.  
The base MMR is best used to understand the average value of a given year, make, model and style. Uses include valuing a portfolio of vehicles where an average is good enough and/or condition, odometer or color may not be known.

Since no two vehicles, sales or markets are the same, the typical range shows how transaction prices for a given year, make, model and style may vary around the base MMR. Based on the statistics of the MMR, we expect about two-thirds of transaction prices to fall within the typical range.
MMR Adjustments provide a breakdown of how odometer, geographic region, condition and exterior color impact a specific vehicle’s value relative to its the base MMR. These adjustments are derived from a statistical analysis of wholesale transaction prices and are recalculated daily for each year, make, model and style. For example, if the average AutoGrade condition for vehicles in the market were to drop from 4.1 to 3.5 over time, with all else being equal, you wouldn’t expect a 3.6 vehicle to get the same adjustment in both cases. Instead, the adjustment would be a deduct from a 4.1, but an add to a 3.5.

The adjusted MMR is the sum of the base MMR plus adjustments, with some rounding.  Use the adjusted MMR to find what a specific vehicle is worth. The adjusted MMR gauge depicts how the adjusted MMR compares to the base MMR and typical range. Use the gauge to see how a specific vehicle’s value compares to other vehicles of the same year, make, model and style.

Vehicles outside of the typical range aren’t “good” or “bad.” The gauge just shows the unit’s value is high or low compared to the average vehicle.  For example, a low-mileage, high-condition vehicle can easily sell for above the typical range, whereas a high-mileage, low-condition vehicle can easily sell for below the typical range.

To provide full transparency and help you identify market trends and insights, recent transaction details are also displayed. Note that the MMR adjustments as described above are usually derived from more transactions than are displayed, since these calculations need larger sample sizes.
The historic average shows the average wholesale transaction price and odometer over three 30-day periods, the past 30 days, 6 months ago and one year ago, for a given year, make, mode and style.

New calculations are performed every night in order to include the most recent sales transactions in the MMR database. The statistical engines analyze every transaction all the MMR values, historical averages, depreciation factors, regional and seasonal adjustments, and price forecasting, are based on the most up-to-date information available.

  • The program begins by gathering all transactions for a specific vehicle.
  • If a statistically sufficient sample cannot be found from the previous 30 days, the statistical models progressively search earlier months until a sufficient number of representative transactions are found. Any auction transactions gathered from earlier months are “aged” to the current month.
  • Outliers are discarded from the sample. For example, the MMR statistical models may exclude a high-mileage vehicle that sold at a significantly higher price than similar vehicles with lower mileage, or a low-mileage car that sold significantly below higher-mileage cars. The MMR also excludes salvage vehicles, specialty vehicles such as boats and motorcycles, heavy trucks, “lemon law vehicles” and vehicles sold in bulk.
  • The statistical engines are very responsive to data integrity and availability. The MMR doesn’t pretend to know something when it doesn’t have the data to back it up.  For example, the MMR does not provide estimates for mileage depreciation and price forecasts if there’s not a sufficient number of recent and statistically reliable transactions. However, the moment reliable data becomes available, the MMR immediately applies the best statistical methods available to estimate MMR values.

The results are different because you are working with a different set of data than the one used by the MMR statistical models. For some vehicles, the difference is slight, but for others it can be substantial.

In addition, the MMR has two components. The first component is the prices and mileage displayed in the MMR. These are pre-calculated by the MMR statistical engines and then displayed in a file that is separate from the auction transactions. Your PC doesn’t calculate the averages; it just displays them. The second component of the MMR is the auction transactions displayed on the Transactions and Auctions summary tabs. These transactions only represent a sample of the previous 30 days of transactions, and are included solely to provide additional information about transactions in the wholesale auction market. These summary tabs are equivalent to a post-sale report with a few sorting features. However, the MMR statistical models base their calculations on all transactions for a specific vehicle, not just the most recent ones listed in the Transactions or Auctions summary tab.

Statistical solutions for calculating averages from small data sets, such as brand new models or seldom-traded vehicles, requires a lot of processing time and horsepower to arrive at accurate averages. This kind of heavy lifting is outside the capabilities of desktop PCs

Vehicle condition is a subjective judgment and the MMR is objective. However, for the convenience of subscribers for whom condition is important, the MMR program simulates condition by showing values and mileages that are estimated above and below the average price and average miles. In the future, the MMR will incorporate objective data, such as condition grades where available, as a parameter for improving the accuracy of the MMR forecast.

Projected or forecasted values are the MMR predictions of prices for the next month. These projections are based on millions of auction transactions that are updated daily. These predictions are the result of the MMR comprehensive forecasting program. The accuracy of the modeling technique is tested daily against the most current actual auction transactions and adjusted based on the best available statistical model.

The MMR estimates the typical average range of retail values based on Cox Automotive retail transactions for a given year, make, model and style. Retail values are shown in MMR only for the convenience of our subscribers who need an approximate retail price. These retail prices are estimated mark-ups of actual wholesale values. However, Manheim does not currently collect data on retail values and recommends users incorporate additional sources of retail information to develop a more accurate estimate for retail prices

The following transactions are considered as invalid transactions: Total Resource Auction (TRA) – Salvage, Mark III, Specialty Vehicles, Collision, Distribution Center, Heavy Truck,  and Salvage Units that are not TRA

All pricing is completed nightly, Monday-Friday. The process begins Monday through Friday evenings beginning at 10pm ET and finishes between 12:30-2:30am ET. The process also runs on Sunday at 4am ET and typically finishes around 7:30am ET.
