Negotiating a used car feels like a personality test. Some people love it, most of us just want a number that isn't insulting. The problem is that "fair price" gets treated as a single figure, when the market doesn't work that way at all.
I went looking for how wide the real spread is. Not across models — within one. Same truck, same year, same mileage bracket.
The same truck, priced 200 ways
Take a 2020 Ford F-150 with 80,000 to 110,000 miles. There are 159 of them in our listings. The average asks $23,589. The spread around that average is ±$7,981 — about 34%.
| Vehicle | Listings | Average ask | Typical spread |
|---|---|---|---|
| Ford F-150 | 159 | $23,589 | ±34% |
| Ford F-150 | 189 | $25,306 | ±27% |
| Ford F-150 | 205 | $24,907 | ±24% |
| RAM 1500 | 165 | $23,058 | ±23% |
| Ford Transit | 146 | $20,937 | ±20% |
Read that again: identical trucks, same age, same miles, and a quarter to a third of price variation between them. That isn't a market with one fair price. That's a market where the seller picked a number.
What that means at the table
It means the asking price carries far less information than people assume — and that the question "is this a good deal?" has an actual answer you can look up instead of guess.
My approach is boring and it works. Before contacting anyone, I check what the model genuinely trades at in that year and mileage on our used value data, so I know where a listing sits in the range. A truck priced at the top of the band needs a reason — low miles, records, something. Absent a reason, that's the gap you're negotiating into.
The second thing I do is separate price from condition. A cheap listing inside a 34% spread is either a bargain or a warning, and the number alone won't tell you which. Running the VIN takes a minute and answers it — open recalls, title status, whether the build matches the ad.
How I'd play it
Don't open with a percentage off. Open with a comparison: what similar trucks in the same mileage band are actually listed at, and where this one sits. Sellers argue with opinions, not with a range.
And know when to walk. With this much spread, there is always another one — 159 of them, in this case. The leverage isn't in your negotiating voice, it's in the fact that you don't need this specific truck.
Frequently asked questions
How much can you negotiate off a used car?
It depends where the listing sits in the range, not on a fixed percentage. Identical trucks at the same year and mileage vary by 20-34% in our listings, so the room depends entirely on the individual ask.
Why do identical used cars have such different prices?
Because sellers set prices individually, with no central reference. Condition, urgency and simple guesswork all feed in, which is why the spread within one model and year is so wide.
Is the cheapest listing always the best deal?
No. Inside a 34% spread the cheapest car is either genuinely good value or carries a problem. Check the VIN for title status and recalls before assuming it is a bargain.

Everyone knows which cars are popular. Far fewer know which popular cars are actually hard to find, and those are different lists — one is about interest, the other about what happens when you go looking.

Everyone assumes the big city is the expensive market and the drive is worth it. Inside three large states the biggest metro is often the cheapest, and the gaps that do exist come from what is parked there rather than local pricing.
