The Copart list cross-referenced against
Export (1).csv and the PDF sales catalog — 837 unique
units — then priced against Copart sold comps net of fees, tow and a
$500 profit target to get a dollar ceiling per car.
Max bid = Copart sold-comp price − Copart fee − tow − $500 profit − competitor buyer fee. Room vs MMR is that ceiling minus book: positive means Copart can pay over book and still clear $500, which is where the real edge is. Tier ranks how much the comps are worth trusting.
Room vs MMR (max bid − book)
Comp confidence tier
An ordered scale centered on the toss-up. To the left the profile favors Copart (low CR, high mileage, low MMR, older vehicle); to the right it favors the competitor. Same scale on both rows — the top one counts cars, the bottom one counts MMR dollars.
Each dot is a vehicle (820 with both odometer and MMR known). The bottom-right corner — cheap and high-mileage — is Copart territory; the top-left is where the competitor wins. MMR axis is logarithmic.
The competitor's 0-to-5 scale. Forty percent of the run sits below 2.0 — the band where a salvage-auction buyer competes better than a retail-remarketing buyer.
Two reads of the same run, in unit counts.
Odometer (miles)
MMR (market value)
Both files describe the same sale, but not the same selection of cars. The union is 837 VINs; either source on its own leaves 155 to 200 units out.
The ten largest by volume. The last column is the share of each consignment where Copart holds the edge — that is how you rank the commercial conversations.
All 125 units that clear the $500 profit target, Tier A first and within a tier the most room against book first. Max bid is the ceiling at the median comp; safe ceiling is the same figure if the car instead sells at the 25th-percentile comp — use that one for Tier B/C or any single-comp row.
