The median asking price for a used BMW 640i is $14,999 across 112 listings. A 2018 costs about $22,872; a 2012 about $12,940. But the same year can differ wildly: among 2018 cars the dearest asks 2.4 times what the cheapest does — condition, mileage and title do the rest.

A spread near 1.5× means the market agrees what a BMW 640i of that year is worth. Past 3× the listings mix tidy examples with tired ones, and a careful buyer can do well — but the exact figure for one car depends on its mileage and history, which is what the valuation tool is for.
Dealer or private seller
Both figures are measured against the median for the same model year, so age is out of the comparison and what remains is the markup itself.

How we count
The BMW 640i figures here come from 112 live listings, 2012–2019 — asking prices, not sale prices. Sellers ask more than they get, so treat these as the top of the range, not the bottom.
Percentages here are never plain averages: each listing is first turned into its ratio against the median for its own model year, and those ratios are averaged instead. Without that step the numbers lie confidently — a flat average across 2012–2019 would mostly measure which years happen to be for sale this week. Slices too thin to survive the test are dropped rather than dressed up with an error bar, which for the BMW 640i leaves 5 model years standing. The full method, with the traps it avoids →
Frequently asked questions
How much does a used BMW 640i cost?
The median asking price is $14,999 across 112 live listings, ranging from about $12,940 for a 2012 to $22,872 for a 2018. These are asking prices — sellers generally accept less.
Why do prices for the same year vary so much?
Among 2018 cars the dearest asks 2.4× 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.
