September’s dealer industry update comes down to three different kinds of change: softer wholesale prices, a major auction acquisition still in progress, and a new way Wisconsin delivers dealer license certificates. Each deserves attention, but they should not be treated as the same kind of news. Cox Automotive · Copart · WisDOT
This update covers September 2026, including September market data released in early October. The acquisition status below is checked through October 8; the practical takeaways are our interpretation, not forecasts of what any individual vehicle will earn.
Wholesale Prices Finished September Below Last Year
Cox Automotive’s full-month report put the September Manheim Used Vehicle Value Index at 205.9, down 1.1% from August and 0.6% from September 2025, after adjustments for vehicle mix, mileage, and seasonality. Cox described September’s depreciation as steeper than typically seen at that time of year. Cox Automotive
The important point for buyers is not just that the overall index declined. The market did not move evenly across every type of vehicle. Cox Automotive
- EVs: The EV index rose 4.3% year over year and 0.6% from August. Cox Automotive
- Non-EVs: The non-EV index fell 1.6% year over year and 1.7% from August. Cox Automotive
- Vehicle segments: Compact cars showed strength, while midsize cars, pickups, and SUVs continued trending down; the report did not give individual percentage changes for those segments. Cox Automotive
Auction activity adds context: sales conversion averaged 55.2%, which was 1.9 percentage points below the recent three-year September average. Wholesale supply ended the month at 28 days, higher than a year earlier but still within seasonal norms. Cox Automotive
What This Means for Your Next Buy
Our takeaway is to stay disciplined rather than assume every lower-priced vehicle is a bargain. Set your bid using current comparable vehicles and your full estimated costs, including auction fees, transportation, reconditioning, and the time you expect to hold it.
Stress-test the deal, too: would it still make sense if your resale price came in below your estimate? That is a planning exercise, not a prediction that a particular car will lose value.
The Manheim index is a broad wholesale-market benchmark, not a quote for your next purchase or a measure of your profit. For the operating side of a wholesale business, explore using your dealer license. Cox Automotive
Copart and ACV: A Pending Deal, Not a Completed Transition
The proposed Copart–ACV transaction remained unfinished as of October 8. Copart’s latest announcement extended its offer to buy ACV shares to 5 p.m. Eastern on October 15, 2026, unless extended again or terminated earlier. Copart’s October 8 Announcement
The company said the extension allowed more time for the federal antitrust waiting period, then scheduled to expire late on October 13. Completion remained subject to the transaction’s conditions; a scheduled deadline should not be read as confirmation that the acquisition has closed. Copart’s October 8 Announcement
For dealers, the distinction matters: the announcement concerns the transaction, not a new set of auction operating rules. That release does not announce changes to customer accounts, buyer fees, or platform access. Copart’s October 8 Announcement
Our takeaway is to separate acquisition headlines from instructions that affect your next purchase. Check the platform’s current terms and official customer notices before assuming that an account, inspection process, or buying procedure has changed.
Wisconsin Dealer License Certificates Move to Email
WisDOT’s August Plain Dealing notice says that, beginning September 1, 2026, dealer license certificates are delivered electronically to the business email address on file with the Dealer and Agent Section. The notice instructs dealers to print the certificate and display it at the business location, citing Wisconsin’s existing display requirement. WisDOT Plain Dealing
If your dealership does not have a business email address on file, WisDOT directs you to contact the Dealer and Agent Section at 608-266-1425 or dealerlicensingunit@dot.wi.gov. This is a certificate-delivery update, not an announcement of expanded license privileges. WisDOT Plain Dealing
Our practical suggestion is straightforward: confirm that the state has the right business inbox, make sure the person responsible for compliance checks it, and follow the printing and display instructions when the certificate arrives. Ask WisDOT directly about a specific application or renewal rather than assuming how the delivery change affects its timing.
Keep the Headlines Connected to Your Business
Our September takeaway is to focus on the details you can control: the numbers behind each bid, the actual terms of the auction you use, and the administrative steps that keep your business organized. A market headline can prompt a useful question, but it should not replace checking the facts for your own transaction.
