MMR Help

About MMR

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, MMR provides users with pricing projections, transactions listing, auctions listing, summary information and a variety of reports based on their selection.

MMR can help you research vehicles quickly and easily - it can target specific vehicles nationally or by region.

Frequently Asked Questions

How do I access MMR?

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

How do the values in MMR compare with traditional guidebooks?

It is not uncommon to find differences between MMR values and guide books. 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. The MMR programs do not use interpolation to compensate for insufficient data. Guide books, which do not have access to the same amount of data as MMR (much less on a daily basis), use editorial expertise and limited market observations to arrive at prices; for this reason, there may be differences.

Why is the mileage different for each vehicle?

Because that's the way it is in the real world. For example, the average family car logs more miles than an expensive weekend-only sports car. MMR obsoletes the old-fashioned "mileage tables" that do not allow for differences in how a vehicle is used. The MMR statistical programs compute a separate average mileage and per-mile depreciation factor for every vehicle in its database.

How are the MMR averages calculated?

New calculations are performed every night in order to include the latest and most recent sales transactions in the MMR database. The statistical engines then analyze every transaction so that, for every vehicle, each MMR value — historical averages, depreciation factors, regional and seasonal adjustments, and price forecasting — is 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.
  • Statistically unreliable records (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. 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. For example, MMR does not provide estimates for mileage depreciation and price forecasts if there is an insufficient number of recent and statistically reliable transactions — MMR doesn't pretend to know something when it doesn't have the data to back it up. However, the moment reliable data becomes available MMR immediately applies the best statistical methods available to estimate MMR values.
  • It is this combination of statistical precision, access to same-day sales transactions, trim level data, historical averages, and depreciation rates, as well as immediate responsiveness to changes in data, that makes MMR so valuable. The resulting values are then presented in MMR.

Why do I get a different result than MMR when I average the transactions?

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

In addition, MMR has two components. The first component is the prices and mileage displayed in MMR. These are pre-calculated by 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 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, 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.

Why does MMR pre-compute averages?

For many reasons, but the most important is that the 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.

How is the vehicle's condition determined?

Vehicle condition is a subjective judgment and 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, MMR will incorporate objective data, such as condition grades where available, as a parameter for improving the accuracy of the MMR forecast.

What does "Projected Values" mean?

Projected or forecasted values are MMR predictions of prices for today, next week, next month and next year. 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.

What is "Estimated Retail"?

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.

When requesting data, which transactions are considered invalid transactions and excluded from MMR?

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

How often is MMR updated?

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 next morning. The process also runs on Sunday morning at 4am ET and typically finishes around 7:30am ET.

Can I sort my search results?

Yes. By clicking on a column heading, you can view the results in ascending or descending order.

Can I view MMR in a pop-up window?

Yes, just click on View in a pop-up window at the top left-hand side of any MMR page, under the main navigation.

I want to print my results out for each vehicle I look at but I only get the lower half or the upper half to print out. How do I print it all at once?

This is because the application uses frames. Try printing using one of these methods:

The Printable Version link in the upper-right corner.
The print option of the browser.

    Click File in the upper-left corner of the browser (or type Ctrl+P).
    Once the print dialog displays, select the Options tab.
    Within Options select As laid out on screen.
    Press Print at the bottom.
