The same build, other model years

Dodge used the VIN pattern 1B3AS56C 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.

1–3 1B3 FCA US LLC · World manufacturer identifier
4–8 AS56C Model, body style, engine and restraint system
9 × Check digit — computed per vehicle, not part of the build
10 4 Model year — 2004
11 × Assembly plant
12–17 ×××××× Production sequence number, unique to each vehicle

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 19 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
