The median asking price for a used Infiniti QX80 is $12,983 across 238 listings. A 2024 costs about $56,937; a 2014 about $9,950.
What each model year costs
Three numbers per year: the cheap end, the middle and the dear end. The gap between them is the useful part — it tells you whether the year has a clear market price or whether condition decides everything.
| Year | Cheap end | Median | Dear end | Spread | Typical mileage |
|---|---|---|---|---|---|
| 2024 | $43,988 | $59,937 | 1.4× | 30,917 mi | |
| 2021 | $23,495 | $32,995 | 1.4× | 95,075 mi | |
| 2020 | $17,999 | $34,950 | 1.9× | 99,342 mi | |
| 2019 | $15,900 | $29,685 | 1.9× | 96,534 mi | |
| 2018 | $12,800 | $17,600 | 1.4× | 153,542 mi | |
| 2017 | $11,995 | $16,790 | 1.4× | 134,738 mi | |
| 2016 | $8,950 | $13,995 | 1.6× | 147,608 mi | |
| 2015 | $7,999 | $13,995 | 1.7× | 158,521 mi | |
| 2014 | $7,900 | $12,990 | 1.6× | 160,719 mi |
A spread near 1.5× means the market agrees what the car is worth. Past 3× it usually means the sample mixes tidy examples with tired ones — and that a careful buyer can do well.
Dealer or private seller
Both figures are measured against the median for the same model year, so age is taken out of the comparison — this is the forecourt markup on its own.
| Seller | Listings | vs median year | Average asked |
|---|---|---|---|
| Dealer | 148 | +2.5% | $16,046 |
| Private seller | 28 | -2.9% | $13,908 |
The gap comes to 5.4 percentage points. Some of that buys something real — reconditioning, a warranty, paperwork handled. The rest is the cost of not looking further.
How fast price falls with mileage
Taken from a single model year — 2017, the one with the most listings — so the curve shows mileage alone rather than age creeping in alongside it.
| Mileage | Average asked | Listings |
|---|---|---|
| 75–100k miles | 5 | |
| 100–125k miles | 9 | |
| 125–150k miles | 26 | |
| 150–175k miles | 7 |
Between the lowest and highest mileage bands the asking price falls 38%. Most of that drop happens early: the first hundred thousand miles cost far more than the second.
Asking prices are the market. What is that car worth?
- Exact value for one VIN, adjusted for its mileage
- Live listings with prices, not just percentiles
- Price-drop alerts on the model you are watching
- Full research report as a PDF you can hand to a mechanic
- No ads, on every page
- No ads, no tracking — and much more
How we count
Every figure comes from live classified listings — asking prices, not sale prices. Sellers ask more than they get, so treat these as the top of the range, not the bottom.
Why the percentages, and not plain averages. This is the part worth explaining, because getting it wrong produces confident nonsense. Take a naive average price per state and you learn that this car costs four times more in Alabama than Indiana — which is false. What actually happened is that Indiana's listings were older cars. Do the same by title and you get the absurd result that rebuilt cars sell for more than clean ones, because the rebuilt ones in the sample happened to be newer.
So we never average prices across a slice. Each listing is first converted into its ratio against the median for its own model year, and those ratios are averaged instead. «Fifteen percent below median» then means what it says, and holds up whichever years the slice happens to contain.
Slices with too few listings are dropped rather than shown with a wide error bar — a percentage built on eight cars is decoration, not data.
