The same build, other model years
Buick used the VIN pattern LRBFZSR4 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 | LRB | SHANGHAI GENERAL MOTORS CORP LTD. · World manufacturer identifier |
| 4–8 | FZSR4 | 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 |

Vehicles of this build
A fixed sample of 3 vehicles carrying this configuration — each with its own history page. The sample refreshes quarterly, not nightly, so it stays put between visits.
Cars are filed by a fixed rule based on the VIN, so a car never moves between groups.
Neighboring configurations
Other factory configurations of the Envision, each with its own build sheet. The set is fixed by the VIN patterns themselves, so it does not shuffle as prices or inventory move.

Prices are asking prices from 123 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 3,263 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
