Data from the newly published June 2026 Manheim Used Vehicle Value Index (MUVVI) highlights a significant stabilization in the U.S. wholesale automotive market, characterized by a sharp performance divergence between powertrain types.
For collision repair facility operators, MSO managers, and insurance appraisers, the index reveals an important structural trend: wholesale used electric vehicle (EV) valuations are significantly outpacing internal combustion engine (ICE) models. Because a vehicle’s pre-accident value directly dictates its total-loss threshold, this valuation spike expands the permissible repair window for damaged EVs landing on shop estimate drives.
Market Index Baselines
The headline MUVVI registered at 212.9 for June 2026 on a mix-, mileage-, and seasonally adjusted basis. While this represents a marginal 0.1% increase relative to May, the index sits 2.1% higher than the baseline documented in June 2025.

[Normalized Q2 Seasonal Line]
The current reading follows an aggressive spring selling cycle fueled by early U.S. tax-refund distributions, which drove wholesale vehicle pricing to its highest levels in several years before plateauing in March. By the close of June, values normalized, settling approximately 1% below that springtime high.
Powertrain Dynamics: EV vs. Non-EV
The standout operational metric in the report is the aggressive appreciation of plug-in assets relative to conventional liquid-fuel powertrains:
- The Wholesale EV Index: Rose 12% year-over-year and gained 1.7% month-over-month compared to May.
- The Non-EV Index: Rose a modest 1.7% year-over-year and ticked upward by just 0.2% month-over-month.
Despite this rapid pricing expansion, fully electric vehicles continue to represent a small sub-segment of wholesale remarketing, accounting for less than 4% of total vehicle allocations processed through Manheim auction lanes.
Wholesale Liquidity and Core Inventory Data
Dealer buying demand remained historically firm throughout June, as measured by secondary auction conversion and inventory cycle metrics:
| Market Performance Indicator | June 2026 Recorded Baseline | Deviation from Historical Trends |
| Auction Sales Conversion Rate | 57.5% conversion on lane runs | 2.6 percentage points above the rolling three-year monthly average. |
| Wholesale Inventory Supply | 26.9 days of available vehicle stock | Increase of 1.3 days versus June 2025; remains within seasonal norms. |
| Non-Adjusted Wholesale Prices | Down 1.3% month-over-month | Accelerated vs. the typical historical June contraction of 0.5%. |
Strategic Perspectives from Cox Automotive
Corporate analysts interpret the data as a return to traditional seasonal rhythms rather than an indicator of structural cooling.
“The first half of the year is officially in the books, and wholesale values finished on solid footing,” stated Jonathan Gregory, senior director of economic and industry insights at Cox Automotive. “The story of the first half is a strong tax-refund season that pushed values to levels we haven’t seen in a few years, peaking in March before normalizing. The bigger picture remains one of balance.”
However, Gregory highlighted specific headwinds tracking into the back half of 2026. A substantial volume of electric vehicles originally written on mid-term commercial leases between 2023 and 2024 are scheduled to return to auction channels as off-lease inventory, creating potential downward pressure on used values. Additionally, if retail gasoline prices continue to soften, consumer demand for secondary EVs could experience a parallel cooling effect as inventory levels normalize.
Jeremy Robb, chief economist at Cox Automotive, noted that the broader marketplace is right-sizing after anomalous spring highs.
“The strong spring driven by tax-refund activity pushed values higher, but recent MUVVI data shows the market settling back into a more typical seasonal pattern,” Robb detailed. The firm’s finalized mid-year macroeconomic forecast projects the MUVVI will close December 2026 approximately 2% higher than the baseline documented at the end of December 2025.
Operational Takeaways for Collision and MSO Management
From a shop management perspective, these shifting index values translate directly into altered total-loss ratios and claim approvals at the front desk:
Balancing Cycle Times Against Valuation Shifts: The projected influx of off-lease EVs in late 2026 means the current high-valuation window for plug-in assets could narrow quickly. Collision facilities should actively prioritize cycle times for high-value EV repairs currently in production to ensure vehicles are completed and billed before potential market value corrections hit insurance calculations.
Expanded EV Repair Thresholds: With used EV wholesale values sitting 12% higher than last summer, insurers have significantly more financial headroom before a vehicle reaches its total-loss threshold (typically 70% to 80% of actual cash value). Complex structural repairs, battery tray inspections, and ADAS sensor array replacements that would have resulted in an immediate total loss last year are now tracking as viable, revenue-generating repair plans.
Estimating Accuracy and Part Sourcing: While higher values keep vehicles out of the salvage yard, non-adjusted wholesale prices fell 1.3% in June alone. Estimators must ensure their estimating platforms use real-time local market data rather than old quarterly figures to prevent discrepancies with insurance adjusters during supplement reviews.
