The median asking price for a used GMC Suburban is $5,500 across 55 listings. A 1999 costs about $6,000; a 1995 about $3,500. But the same year can differ wildly: among 1999 cars the dearest asks 12.3 times what the cheapest does — condition, mileage and title do the rest.
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 |
|---|---|---|---|---|---|
| 1999 | $1,200 | $14,799 | 12.3× | 175,644 mi | |
| 1995 | $2,800 | $12,500 | 4.5× | 185,884 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 |
|---|---|---|---|
| Private seller | 26 | +22.7% | $5,738 |

- Live listings with prices, not just percentiles
- Price-drop alerts on the model you are watching

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.

Frequently asked questions
How much does a used GMC Suburban cost?
The median asking price is $5,500 across 55 live listings, ranging from about $3,500 for a 1995 to $6,000 for a 1999. These are asking prices — sellers generally accept less.
Why do prices for the same year vary so much?
Among 1999 cars the dearest asks 12.3× what the cheapest does. Mileage, service history and title status explain most of it — which is why an average price for an older car tells you very little on its own.
