The two numbers answer different questions. MMR tells you what dealers paid for cars like this one at auction, before fees. The ask tells you what one seller hopes to get. Before you call, you want to know how much of the distance between them your own costs explain, and how much is room to negotiate.
What MMR measures
The Manheim Market Report is Manheim's wholesale price guide, built from sales at Manheim auctions in the U.S. and Canada. Manheim's MMR help page, read September 29, 2026, gives the method. The base MMR is "the average wholesale price, odometer, condition grade and build quality of recent transactions for a given year, excluding outliers." Recent sales count for more than older ones. The adjusted MMR corrects the base for odometer, region, condition and exterior color.
The same page lists what MMR leaves out and when it goes thin:
- Sales through Manheim's salvage and collision channels don't count, and neither do cars with title brands or fewer than 50 miles.
- A trim needs at least 6 sales in the past year and at least 2 in the past 90 days to get its own MMR. Below that, Manheim may estimate a value from related trims and show it with a "Small Sample Size" icon.
- Manheim recomputes the values nightly.
MMR is a hammer price. It does not include the buy fee you pay the auction, the transport to your lot, or any post-sale inspection. It also sits behind a Manheim account login, which private sellers don't have.
What a private-party ask is
The ask is the number the seller typed into Craigslist, Facebook Marketplace or OfferUp. It is a hope, not a sale. Sellers set it from dealer listings they found, from a Kelley Blue Book lookup, from what they still owe, or from what they paid. Some pad it because they expect to be talked down. Some write "firm" and mean it.
The ask also moves. A car listed three weeks with two price cuts tells you more than the first number did. Everything else in the ad is what the seller says: the miles, the trim, the title and the condition. Nobody has checked any of it yet.
What KBB's private-party value is
Kelley Blue Book's private-party value is an estimate, not a sale. KBB's value definitions, read September 29, 2026, call it "the starting point for negotiation of a used-car sale between a private buyer and seller" and an "as is" value with no warranty. The private-party range is KBB's estimate of what a seller "can reasonably expect to receive this week."
The same page says KBB's trade-in value will likely be less than its private-party value, because the dealer who resells the car pays for safety inspections, reconditioning and other costs of doing business. That spread is the reason your offer and the seller's printout rarely match.
What a retail ask is
A retail ask is a dealer's listing price. KBB's version, the Typical Listing Price, "assumes that the vehicle has been fully reconditioned and has a clean title history" and includes the dealer's profit, advertising, commissions and other costs. Retail asks are asks too. KBB notes the final sale price will likely be less.
The four numbers side by side
| Number | Who sets it | A real sale | What it includes |
|---|---|---|---|
| MMR | Manheim, from its auction sales | Yes, averaged and adjusted | The hammer price only, before buy fee and transport |
| KBB private-party value | Kelley Blue Book | No, an estimate | An as-is car with no warranty, before taxes and fees |
| Private-party ask | The seller | No, a hope | Whatever the seller wants for it |
| Retail ask | A dealer | No, an ask | Recon, a clean title, the dealer's costs and profit |
Why the ask sits above wholesale
Dealers at an auction bid knowing they still have to recondition the car, hold it and sell it. MMR records what they paid after allowing for all of that. The private seller has none of those costs and compares the car to retail listings and to KBB. An owner who asks less than a dealer's retail price and more than MMR is pricing the car rationally from their side of the deal.
So an ask above MMR doesn't make a car a bad buy. The question is how far above, and how much of that gap you would have paid anyway to buy the same car at auction.
How to read the gap before you call
- Put your auction costs on top of MMR. An auction car costs you MMR plus the buy fee, transport and any inspection. Fees vary by auction and account. One published example is Big Valley Auto Auction in Donna, Texas, whose 2026 schedule, checked September 29, 2026, charges a $405 buy fee on a car that sells for $10,000 to $10,999 and $115 for a post-sale inspection on a green-light car. A private ask equal to MMR plus your delivered auction costs is the same money as buying at auction, before condition.
- Check the count behind the MMR. A value built from 6 sales in a year is a weaker fact than one built from 60 sales last month. If Manheim flags a small sample or estimated the value from other trims, give the gap less weight.
- Match the trim and the miles. MMR is priced by trim. Private ads often leave the trim out or type it into the model name, and the miles are what the seller typed. Pull the MMR for the trim you think the car is, adjust it for the stated miles, and plan to confirm both at the car.
- Price the condition. The adjusted MMR uses a condition grade from an inspection. A private car has no grade until you see it. The ad's own words are your first clue. "Check engine light on" or "needs a transmission" means you subtract at least the repair from the MMR you pulled.
- Check the title. MMR drops title-branded sales, so a clean-title MMR overstates a salvage or rebuilt car. See title problems on private-party cars for what each brand does to resale.
- Read the seller's movement. Days listed, price cuts and words such as "OBO," "must sell" or "firm" tell you how close the ask is to a sale.
If the ask still sits well above MMR plus your auction costs, with no condition or title reason to explain it, the seller is pricing toward retail and the call is a negotiation. If the ask sits near or below MMR plus costs, with nothing wrong in the ad, call quickly, because other dealers are reading the same ad.
Retail comps, and MMR as your floor
MMR tells you what the car costs at auction. It says nothing about what the car brings on your lot. For that you need retail comps: dealer listings for the same year, trim and mileage band in your market, and your own sold history. The spread between your buy and your retail sale pays for recon, holding and your gross. The guide to pricing a private-party buy works backward from the retail sale to a maximum buy price.
MMR matters again as your floor. If the car doesn't sell and you wholesale it out, MMR less the auction's sell fee and the trip there is roughly what you get back. The distance between what you paid and that floor is your risk on the car.
What VinCount shows, and what it is adding
VinCount's sheet shows the private-party cars it collects in Los Angeles from Craigslist, Facebook Marketplace and OfferUp with each one's ask, the ask's trend, its price drops and how long it has been listed. It shows the miles, the title flag and "the ad says" tags as the seller's claims. How it works explains each column.
VinCount is adding an auction median beside each ask, with the count of sales behind it, and retail asks for the same car. Those are not on the sheet yet. The count will sit next to the median because a median from three sales and a median from sixty are different facts. VinCount will not turn the gap into a score or an offer. You know your recon, your lot and your turn, and the math is yours.
