The prevailing read on this year’s petrol price spike is that it rattled American consumers and reshaped their vehicle preferences. Used EV wholesale prices tell a rather different story, one in which dealers, not consumers, were the ones who panicked, and paid for it.
How Used EV Wholesale Prices Became the Dealers’ Own Trade
From February through mid-May, as petrol prices climbed, dealers flooded wholesale auctions and bid aggressively on used battery-electric vehicles, evidently convinced that consumers were about to defect en masse from internal combustion. The logic was intuitive enough: high prices at the pump, surging interest in cars that never visit a pump. The data, however, did not cooperate.
According to the Wolf Street analysis of the Manheim Used Vehicle Value Index, used EV wholesale prices rose 11.5% on a seasonally adjusted basis between February and June, the sharpest such move since the supply-chain chaos of 2021 and 2022. Over the same period, prices of non-EVs (which include hybrids and all other internal combustion engine vehicles) dipped a modest 0.3%. Then, in July and August combined, used EV wholesale prices plunged 6.6% seasonally adjusted, surrendering all but the February portion of the five-month run-up. Non-EV prices fell only 1.7% across those two months.
Manheim, a subsidiary of Cox Automotive and the largest auto-auction house in the United States, publishes the index that dealers and analysts rely on to track used vehicle values. Supply at these auctions arrives from rental fleets retiring vehicles, finance companies offloading off-lease inventory and repossessions, and corporate and government fleets cycling out older stock. Dealers buy at auction to replenish retail lots.
The round trip in used EV wholesale prices across those six months amounts to an expensive lesson in the difference between consumer sentiment and consumer behaviour.
Petrol’s Share of Spending Is Not What It Was
The deeper issue is structural, and the numbers make it harder to argue with. In 1972, just before the 1974 oil crisis, roughly 4% of total US consumer spending went to petrol and other energy goods. By 1980 that share had climbed above 6%. Since then, more fuel-efficient vehicles and fewer miles driven per capita pushed per-capita petrol consumption from a peak of 42 gallons per month in 1978 down to 33 gallons per month in 2025. Meanwhile, spending on housing, healthcare and other services has expanded to dwarf the energy line.
In the six months through January 2026, before the price spike arrived, petrol and other energy goods accounted for just 2% of total consumer spending. At the peak of the spike, in April 2026, that share reached nearly 2.5%, before slipping back to 2.2% by July. The national average price of regular unleaded was just under $4.10 per gallon as of 30 July, according to WardsAuto.
A half-percentage-point swing in spending share is real money at the household level. It is not, however, the kind of structural shock that reorders long-term vehicle purchasing decisions. Large pickups with poor fuel economy continue to dominate the new-vehicle market. The petrol price spike did not change that, and there is no particular reason to have expected it would.
The EV Index for July stood at 211.6, up 10.5% against the same month a year earlier, per WardsAuto. The Non-EV Index, by contrast, reached 149.3, a rise of just 0.4% year-on-year. The gap between those two index readings is not evidence of surging consumer demand for used EVs; it is largely the residue of the dealer-driven auction frenzy that began in February and is now unwinding.
There is one further context point worth holding alongside all of this. The federal tax credit that had incentivised new EV purchases was no longer available as of 30 September 2025, per WardsAuto. Dealers calculating that petrol prices would push buyers toward used EVs were doing so in a policy environment that had already removed one of the key financial levers supporting EV adoption. That the wholesale market ran up anyway, then corrected, suggests the trade was built on a narrative rather than a fundamental demand shift.
The irony is precise: dealers who make considerable margins on large, fuel-hungry vehicles convinced themselves that their own customers were about to abandon those vehicles because of a petrol price move that amounted to roughly 0.5% of their total spending. Used EV wholesale prices spiked because dealers believed the moaning and groaning. Consumers, it turns out, were just moaning and groaning.
