Used BMW X6 M asking prices fall 3.2% from July to October

Comparable used BMW X6 Ms (same trim, model year and miles) asked 3.2% less in October 2026 than in July, in listings we tracked through Oct. 1.

That ranks fourth among the 11 models we track that are moving down. Another 24 of the 49 models with a trend were flat. Within BMW, the M3 rose 1.6% over the same months, while the M5 held steady.

The monthly asking price level shows the shape of it. It climbed to 104.3 in June, then slid every month to 100 in October.

A cool market gives buyers room

There are 214 X6 Ms for sale, and we rate the market cool. A typical car takes 51 days to leave the market, and the cars listed would last about three months at the recent pace.

Sellers are already bending. 39% of cars had a price cut in the last 90 days, and the median cut was 2.8%. Still, 67 of the 214 are priced over fair value, so the cuts have not reached everyone.

Trim drives the spread. The 153 base cars have a median ask of $38,400, while the 61 Competition cars have a median ask of $100,000. Asking prices step down with age too: a 2023 is typically listed at about 82% of a 2025's price.

The best deals are 2022 and 2023 cars

By our ratings, which compare each ask with fair value from comparable listings (the X6 M price guide has the ranges), 36 cars are great deals and 28 are good deals. Two of the best are in Springfield, New Jersey.

A black 2023 X6 M with 38,924 miles is listed at $61,822, about $12,500 under its fair value. It has been listed 44 days and cut twice, down 11.6% from its first price, most recently on Oct. 1.

A gray 2022 with 34,882 miles asks $59,723, about $10,500 under fair value. It has been listed 30 days with no price cut on record. Both are among the Gen III X6 Ms for sale.

A 2017 Gen II is marked down too

Older cars show the same pattern. A black 2017 with 64,123 miles in Irvington, New Jersey, asks $25,921, about $5,500 under fair value, and is one of the Gen II X6 Ms listed. It has been cut twice, down 8.9% from its first price.

At 55 days listed, it is worth asking for a lower price. Eighty-four new listings arrived in the last 30 days, so the pool keeps refilling, and the latest price drops show which cars are being cut.
