What Is MMR? Manheim Market Report and Your Trade-In
Published
The short answer
MMR, the Manheim Market Report, is a wholesale value tool that Manheim provides to its subscribers. Manheim says MMR prices are based exclusively on millions of actual sales, updated daily, and that an adjusted MMR equals a base wholesale average plus adjustments for odometer, region, condition, and exterior color. When you hear a dealer mention "MMR," they're usually talking about what similar cars have recently sold for at wholesale — not a retail sticker price. That's one reason dealer offers can differ: each dealer reads the same car's mileage, condition, and resale plans a little differently, which is why it pays to compare more than one offer.
Base MMR is the average wholesale price, odometer, condition grade, and build quality of recent transactions for a given year, excluding outliers. Recent sales are weighted more heavily.
Adjustments show how odometer, geographic region, condition, and exterior color change a vehicle's value relative to the base MMR. The adjusted MMR is the base plus those adjustments.
Mileage: MMR computes a separate average mileage and per-mile depreciation factor for each vehicle rather than using a one-size mileage table.
Condition: Manheim says condition is subjective, so MMR shows values above and below average and incorporates its AutoGrade condition score (plus an EV battery health score for qualifying EVs when available).
Updates: Values are recalculated nightly Monday through Friday, with an additional Sunday run.
Minimum data: An MMR needs at least 6 transactions in the past year and 2 in the past 90 days for that trim. Otherwise it may be estimated and flagged “Small Sample Size.”
Exclusions: Salvage units, lemon-law and other title brands, and units under 50 miles are excluded.
Retail is separate: Manheim's “Estimated Retail” is an estimated mark-up over wholesale, and Manheim advises users to consult other retail sources because it doesn't collect retail value data.
What that means when you sell or trade in
A few practical takeaways for Texas sellers (our reading of Manheim's methodology, not a dealer rule):
Mileage and condition move the number most visibly. Those are explicit MMR adjustments. Bring service records and fix small, cheap issues before an appraisal — see the dealer appraisal prep checklist.
Branded titles sit outside MMR's normal data. If your title is rebuilt or salvage, expect a different conversation; we covered that in selling a rebuilt or salvage title car.
Wholesale isn't retail. A dealer that buys your car has to recondition and resell it. An offer near wholesale value can be a fair number even if it's below what a similar car is listed for on a lot.
Values change daily. Because MMR recalculates nightly and weights recent sales more heavily, an offer from three weeks ago may not match today's.
Why comparing offers matters more than a single number
MMR is a reference point, not a price tag. Two dealers can start from similar wholesale data and still land on different offers because one needs your model for its lot and the other plans to wholesale it. The way to find out is to ask more than one dealer after a physical appraisal.
PriceForMyTrade connects vehicle sellers with local dealerships that compete for the car:
Submitting a request takes about 30 seconds. Getting an offer doesn't happen in 30 seconds.
Competition is handled manually, and dealers contact you directly. First responses typically come the same day, but timing isn't guaranteed.
Offers are confirmed after a physical appraisal.
Dealers can buy outright. You don't have to buy another vehicle.
It's free to sellers. Participating dealerships pay for enquiries.
MMR is Manheim's wholesale benchmark, built from actual auction sales and adjusted for mileage, region, condition, and color. It explains part of how dealers think about a trade, but it isn't your offer. Prepare the car, then let several dealers appraise it and compete.
