A used Cadillac Escalade IQ sat for 128.7 days before selling in September 2026, the slowest of any electric vehicle in an iSeeCars study. The average used EV in the same data sold in 41.9 days, which makes the big Cadillac about three times slower than the typical electric car. Used gas vehicles, meanwhile, slowed to 54.8 days, so the segment that was once the slow-moving one has become the quicker seller on average.

The ranking shows a market splitting by body style. Compact and midsize crossovers move quickly, while full-size electric trucks and SUVs linger, and the pattern is dominated by a single automaker at the slow end. The difference between the slowest and the fastest model in the study is close to a hundred days, a wide gap for vehicles in the same fuel category.
Six GM models among the ten slowest sellers
iSeeCars, which published the analysis on October 28, 2026, ranked used EVs by days to sell using listings of one- to five-year-old vehicles. After the Escalade IQ, the slowest were the GMC Sierra EV at 93.2 days, the Chevrolet Silverado EV at 89.1, the Volvo EX90 at 80.2, the electric Dodge Charger at 80.1 and the GMC Hummer EV SUV at 78.9.
The rest of the bottom ten, in descending order of wait: the Mercedes-Benz EQE at 77.2 days, the GMC Hummer EV pickup at 76.6, the Porsche Macan at 62.6 and the Cadillac Optiq at 61.6. Counting the Escalade IQ, six of the ten are General Motors products. Autoblog’s Adam Lynton, who summarized the findings on November 2, notes that large SUVs and pickups crowd the slow end and that his source does not explain why individual models sell at different speeds.
The raw wait is easy to underestimate. At 128.7 days, a used Escalade IQ sits on a lot for more than four months, while the Silverado EV and Sierra EV need roughly three. Autoblog describes electric pickups and large SUVs as taking three to four months, a slight stretch at the low end, since the listed figures for the pickups and large SUVs run from 76.6 to 128.7 days, or about two and a half to four months.
What iSeeCars counted and left out
The study covers more than 1.5 million used cars aged one to five years that sold in September 2025 and September 2026, which gives the model-level averages a large base to draw on. Average list prices and days to sell were aggregated by model and compared across the two periods. iSeeCars excluded heavy-duty vehicles, low-volume models, models discontinued before the 2025 model year and vehicles built for fewer than four of the last five model years.
The exclusions mean the Escalade IQ cleared the bar for inclusion: it is not a low-volume model by iSeeCars’ definition, so its 128.7 days is a measured figure from a vehicle with enough used listings to rank. iSeeCars puts the gap at 3.1 times the used EV average.
High gas prices and a faster-moving EV market
Karl Brauer, iSeeCars executive analyst, tied the broader shift to fuel costs, saying high-value, well-executed used EVs are benefiting from persistently high gas prices. AAA’s figures fit that story, and they matter because the study period is a single month of unusually expensive fuel: September 2026 averaged $4.33 a gallon for regular, 50 cents above the previous September record of $3.83 set in 2023.
Year over year, the used EV market sped up by 10.1 percent, from 46.6 days to 41.9, while used gas cars slowed by 19.9 percent, from 45.7 days to 54.8. Luxury badges did not predict the outcome. The Audi Q4 Sportback e-tron sold in 29.8 days, while the Cadillac Optiq, also a luxury compact crossover, took 61.6, twice as long.
The fast end of the list is crossover-heavy. The Audi Q4 Sportback e-tron led at 29.8 days, followed by the Toyota bZ4X at 33.3 and the Lexus RZ 300e at 34.3. Used EVs overall also grew more expensive, which means the quick sellers are not winning on discounts, a trend Autoblog tracked in its earlier piece on used EV prices jumping nearly 10 percent.
The price of entry is also shifting. The average used EV rose 9.8 percent to $32,533, about $579 above the average used gas car, so the old rule that an electric vehicle sells cheaper secondhand no longer holds on average. The cheaper, quicker-selling crossovers are the ones where competition for a listing is highest, and Autoblog’s advice for those buyers is to expect competition and not to bank on prices dropping while they wait.
Shoppers aiming at electric pickups and large SUVs face a different calculation. Autoblog says these buyers have more time to compare listings, and its guide to the best large SUVs shows what else competes for the money. The study also leaves a practical matter unanswered. The question is whether the Escalade IQ’s long wait forces price cuts, since iSeeCars’ report on days to sell does not break out asking-price movement for the model.
