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 WP0 DR. ING. H.C.F. PORSCHE AG · World manufacturer identifier
4–8 CA299 Model, body style, engine and restraint system
9 × Check digit — computed per vehicle, not part of the build
10 W Model year — 1998
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.

Prices are asking prices from 24 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 85 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
