Surge in Wholesale Prices Slowing Thursday June 17, 2021 2 min Read Wholesale used vehicle prices (on a mix-, mileage-, and seasonally adjusted basis) increased 0.29% in the first 15 days of June compared to the month of May. This brought the mid-month Manheim Used Vehicle Value Index to 203.6, a 36.4% increase from June 2020. Click image to enlarge. Manheim Market Report (MMR) prices continued to increase but at a decelerating pace in the first two weeks of June. The Three-Year-Old MMR Index, which represents the largest model year cohort at auction, experienced a 0.8% cumulative increase over the last two weeks, with last week recording the lowest weekly increase in 20 weeks. Over the first 15 days of June, MMR Retention, which is the average difference in price relative to current MMR, averaged 99.6%. This indicates valuation models are more closely reflecting market prices than we have seen since early January. The sales conversion rate declined in the first half of June relative to May but remained elevated from historical norms. Sales efficiency last week was more than 6 percentage points higher than the average sales efficiency in June 2019. The latest trends in the key indicators suggest wholesale used vehicle values likely peaked last week. On a year-over-year basis, all major market segments saw seasonally adjusted price increases in the first 15 days of June. Pickup trucks and vans outperformed the overall market, while most other major segments underperformed the overall market. Access the Mid-Month Update for the full report.
