How to read these numbers
“Days of supply” answers a simple question: at the recent pace of sales, how many days would it take to sell every car currently sitting on lots? The industry as a whole sat at 82 days in September 2026 (Cox Automotive), that's the line. Anything far above it is a car dealers are struggling to move. The list below uses CarEdge's October 1, 2026 market day supply figures, filtered to passenger cars and SUVs with at least 1,000 vehicles on lots nationwide. The unfiltered ranking is topped by rare luxury models and commercial trucks most shoppers will never cross-shop.
| Model | Days of supply | Cars on lots | Avg. listing price | Why it's sitting |
|---|---|---|---|---|
| Mercedes-Benz GLB | 419 | 4,642 | $52,491 | A redesigned GLB is on the way, and the current one carries a luxury price in a value-conscious market. |
| Porsche Cayenne Coupe | 263 | 1,863 | $137,427 | Price. Cars over $80,000 sit the longest of any price group (Cox Automotive). |
| Jeep Grand Wagoneer L | 248 | 3,129 | $83,363 | A big price tag from the brand carrying the industry's heaviest inventory. |
| Dodge Charger | 245 | 8,639 | $54,814 | Buyers passed on the electric Daytona, its sales fell 92% in a year, while the gasoline version outsells it roughly 15 to 1. |
| Chevrolet Blazer EV | 238 | 2,296 | $46,929 | One of the specific electric models still clearing a pileup after the federal EV tax credit ended in September 2025. |
| Jeep Grand Wagoneer | 233 | 9,887 | $77,631 | Same story as the longer L version above: price, plus a brand-wide pileup. |
| Kia EV3 | 232 | 1,331 | $38,483 | A brand-new electric nameplate getting a slow start. |
| Porsche Taycan | 219 | 1,001 | $148,579 | The most expensive car on this list, price, plus a cooling top end of the EV market. |
| Jeep Gladiator | 200 | 15,768 | $49,160 | Nearly 16,000 unsold. Jeep simply built far more than buyers asked for. |
| Jeep Compass | 190 | 18,674 | $33,615 | The most cars sitting of anything on this list, and the cheapest, which is why it gets the worked example below. |
| Volkswagen ID.4 | 184 | 1,046 | $45,340 | Production ended in April 2026 with a replacement announced. VW offered a $12,500 bonus on leftover 2025 models through November 2, 2026. |
| Mercedes-Benz CLA | 182 | 3,818 | $53,373 | A small sedan wearing a big-sedan price. |
How long these cars are sitting on dealer lots
Days of supply, October 1, 2026, the same numbers as the table above. At the recent pace of sales, this is how long it would take to sell every car already sitting on lots. The typical new car sits 82 days.
The longer the bar, the longer the car is sitting. Every car on this list is sitting more than twice as long as the typical new car.
Cox Automotive's September 2026 count, a different yardstick pointing the same direction, put the Jeep Grand Cherokee at 179 days of supply, the Jeep Wrangler at 162 and the Ram 1500 pickup at 142. The Toyota RAV4, for comparison: 24 days. If you shop trucks and big SUVs, those three are the pileups.
Why they sit
- The price ladder. Cox grouped September supply by price: cars under $30,000 sat 63 days; cars over $80,000 sat 111. Money is tight, so expensive cars wait. Twenty of the twenty-five slowest models in the full ranking average over $50,000.
- One brand built too many. Jeep carried 169 days of supply in September, Ram 152 and Dodge 149, against Toyota's 35 (Cox Automotive). Five of the twelve cars in the table above wear a Jeep or Dodge badge.
- A replacement is coming. The ID.4's production is over and its successor is announced; a redesigned GLB is on the way. Shoppers wait for the new one, so the current one waits too.
- Specific EVs, not EVs in general. The $7,500 federal EV tax credit ended September 30, 2025, and a handful of electric models are still clearing the pileup that followed. But by September 2026 the average new EV sat 68 days, less than the average gasoline car at 78. It's model by model now, not the whole category.
What a sitting car costs the dealer
Dealers borrow the money for the cars on their lot, it's called floorplan financing, and they pay interest on every car, every day, until it sells. Industry figures from vAuto put the average holding cost at $7.90 per car per day in early 2025: about $237 a month, roughly $700 across 90 days. On the $55,000–$85,000 cars near the top of this list, interest alone runs roughly $370–$640 per car, per month. And once a car passes roughly 90–120 days, lenders typically make the dealer start paying the loan down out of pocket.
That's the engine behind every “manager's special”: a sitting car is a bill that arrives monthly, and the discount that finally moves it is often smaller than the interest already paid on it.
Do the discounts actually show up?
Usually, yes, with one honest warning below. WardsAuto's analysis of dealer pricing found that cars which eventually sell typically go through three to four price reductions, and once a car is past 100 days the total cut often passes $6,000. A dealer-consultant rule of thumb prices aged stock about 3% under market at 60 days, 6% at 90 days and 10% at 120 days.
The extreme case showed what the ceiling looked like: Volkswagen's $12,500 customer bonus on leftover 2025 ID.4s, about 28% of the sticker price, ran through November 2, 2026, to clear the last of a discontinued model.
A long sit raises the odds of a real discount. It promises nothing at any specific dealership. Average incentives across the whole industry in September 2026 were 6.6% of the average transaction price, down from 7.3% a year earlier (Kelley Blue Book). The Charger has been discounted hard all year without clearing its lots. And Edmunds' fall 2026 guidance to shoppers was blunt: don't assume a massive year-end blowout is coming.
What a discount does to the five-year math
This is where a slow seller connects to everything else on this site. Take the Jeep Compass from the table, average listing price $33,615, and run it through the true-cost calculator using the standard assumptions used across this site: 7% sales tax, $5,000 down, a 60-month loan at 6.5%, and the car's resale value held at $16,100 in both runs.
A discount is bigger than it looks on the windshield, because the purchase price feeds the tax, the loan and the interest all at once. It's also smaller than it looks if it evaporates in resale value, which is the other side of this page. The same discount math, applied to a year-end price cut instead of a slow seller: what a December discount is really worth over five years.
The other side of a slow seller
Cars that sit unsold when new often keep sliding in value afterward; slow demand doesn't stop at the dealership door. A $3,000 discount doesn't help if the car loses $4,000 more than a popular model over the same five years. That's why the resale line in the calculator matters as much as the price line, run both numbers before deciding what a “deal” is worth. The depreciation guide shows how fast different kinds of cars fall. On the other side of the coin, see what cars hold their value best.

Formula
Days of supply is the number of cars physically sitting on dealer lots divided by the recent daily sales pace. It answers how many days it would take to sell every car already on lots if sales kept running at the recent pace. Vehicles still in transit are excluded. The list ranks passenger cars and SUVs by that number, highest first, and keeps only models with at least 1,000 vehicles on lots nationwide. The unfiltered ranking also includes low-volume luxury models, work vans and commercial trucks.
The line for comparison is the industry as a whole, which sat at 82 days in September 2026 (Cox Automotive). Anything far above it is a car dealers are struggling to move. Every car in the table sits more than twice as long as the typical new car.
The worked example runs the Jeep Compass through the five-year math twice, once at its average listing price of $33,615 and once at $30,615, which is $3,000 off. The five-year true cost is $51,272 at the full price and $47,504 at the discounted price, a difference of $3,768. That difference is the $3,000 discount, plus $210 less sales tax and $558 less loan interest. The purchase price feeds the tax, the loan and the interest all at once, so a discount is bigger than it looks on the windshield.

Common questions
What does days of supply mean? Days of supply answers a simple question: at the recent pace of sales, how many days would it take to sell every car currently sitting on lots? The industry as a whole sat at 82 days in September 2026 (Cox Automotive), that's the line. Anything far above it is a car dealers are struggling to move.
Which car is sitting the longest right now? The Mercedes-Benz GLB, at 419 days of supply, with 4,642 cars on lots and an average listing price of $52,491. A redesigned GLB is on the way, and the current one carries a luxury price in a value-conscious market.
Why do slow-selling cars get discounted? Dealers borrow the money for the cars on their lot, it's called floorplan financing, and they pay interest on every car, every day, until it sells. Industry figures from vAuto put the average holding cost at $7.90 per car per day in early 2025: about $237 a month, roughly $700 across 90 days.
Does a long sit guarantee a big discount? A long sit raises the odds of a real discount. It promises nothing at any specific dealership. Average incentives across the whole industry in September 2026 were 6.6% of the average transaction price, down from 7.3% a year earlier (Kelley Blue Book).
What does a $3,000 discount do to the five-year cost? Take the Jeep Compass from the table, average listing price $33,615. At $33,615 the five-year true cost is $51,272, about $855 a month over five years. At $30,615, $3,000 off, the five-year true cost is $47,504, about $792 a month over five years. The difference is $3,768 over five years, the $3,000 discount, plus $210 less sales tax and $558 less loan interest.
