The Manheim Index sat at 210 in July 2026, up 1.3% year over year and down 1.4% for the month. Mid-August came in at 207.4, roughly flat against the same point last year. The peak was March.
Reading it without the spin
Flat year over year is not a crash and nobody should sell it as one. What it is, is the end of a direction. For most of the last several years a dealer holding a unit slightly too long had appreciation quietly working for him. That is over, and it has been over since spring.
Aged inventory now costs exactly what the calendar says it costs, with nothing underneath it.
The market used to bail out a slow turn. It does not now.
What to do with it
It raises the price of buying wrong. In an appreciating market a unit bought three hundred over could be rescued by waiting. In a flat-to-softening one, waiting is the thing that costs you. The margin has to be there on day one because nothing downstream is going to add to it.
Which is the same conclusion the gross data reaches from the other direction. Both roads end at the buy.
