The essentials, explained
As filed by BMW with NHTSA for this VIN pattern. Fields the filing does not record are left out entirely — a missing row means no recorded value, not a missing feature.
Gross vehicle weight rating is the loaded ceiling set by the manufacturer, not the car's own weight.
Systems the filing does not record are not listed above. Check the window sticker of the exact car before you rely on any single feature.
The market for this VIN pattern
Asking prices from dealer listings associated with this VIN pattern in the United States. Mileage, condition, options and location can change the value of an individual vehicle.
$29,999 median asking price · 7 listings · as of Sep 6, 2026
Too few listings to publish a price range — with 7 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.
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.
VIN positions 1 through 8 read WBS3U9C3 and position 10 reads H. Those nine characters define this build. Position 9 and positions 11 through 17 describe the check digit, assembly plant and production sequence; they are not part of this pattern.
| Positions | Characters | What they encode |
|---|---|---|
| 1–3 | WBS | BMW M GMBH · World manufacturer identifier |
| 4–8 | 3U9C3 | Model, body style, engine and restraint system |
| 9 | × | Check digit — computed per vehicle, not part of the build |
| 10 | H | Model year — 2017 |
| 11 | × | Assembly plant |
| 12–17 | ×××××× | Production sequence number, unique to each vehicle |
