What this build asks today

Asking prices of live dealer listings decoded to this exact configuration — narrower than the trim-level figure, because every car counted here shares the same engine, transmission and drivetrain.

$39,206 median asking price · 6 listings · as of Aug 30, 2026

Too few listings to publish a price range — with 6 cars on the market, the cheapest and the dearest are single cars, not a spread. The median above is what they ask in the middle.

The same build, other model years

BMW used the VIN pattern WBA5U7C0 for 3 model years. Nothing but the year changes between these pages, so the price gap between them is depreciation on an identical car.

How this VIN pattern is read

A 17-character VIN carries two kinds of information: what was built, and which one it is. This page is the first kind — the nine highlighted positions.

Positions Characters What they encode
1–3 WBA BMW AG · World manufacturer identifier
4–8 5U7C0 Model, body style, engine and restraint system
9 × Check digit — computed per vehicle, not part of the build
10 M Model year — 2021
11 × Assembly plant
12–17 ×××××× Production sequence number, unique to each vehicle

119 vehicles carry this build

Where this data comes from

Specification fields are decoded from the manufacturer's filings in the NHTSA vPIC database, keyed on VIN positions 1–8 and 10. We publish the filed values as they stand and leave out anything the filing does not record.

Prices are asking prices from 6 live dealer listings decoded to this build , last updated August 30, 2026 . They are what sellers ask, not what buyers paid.

Vehicle counts come from the 119 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
