The same build, other model years
Lexus used the VIN pattern JTHAA5BC for 4 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 | JTH | TOYOTA MOTOR CORPORATION · World manufacturer identifier |
| 4–8 | AA5BC | 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 |
170 vehicles carry this build
Every VIN we have decoded to JTHAA5BC-M shares the specification above.

Cars are filed by a fixed rule based on the VIN, so a car never moves between groups.

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.
Vehicle counts come from the 170 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
