Valuation + Forensic Report
Decoded from the vehicle's data plate / trim tag against the marque's factory code tables — establishes factory-documented specification. Confirm the tag is original and unaltered; decode is identity, not a value.
Where the factory stamped the engine and driveline numbers for this marque, and how to read them — so you can confirm the car is matching-numbers against its documentation. Identity / how to verify, never a value.
Your inputs place the car above our independent baseline. The gap is the condition premium you're claiming — defensible if the paint, interior and service history support a #2.
Realized closes span $64,250–$79,500. A high bid to $83,000 tested the top without clearing — demand is probing the ceiling. Recent prices are trending up.
Grounded in 4 transaction(s) (3 sold / 1 bid-to), most recent 2026-05-01. Illustrative sample evidence — shown to demonstrate the format.
This is the market evidence that corroborates the estimate — the sales themselves, not our weighting. The number above is produced by the Parclines valuation model; the evidence shows what the market has actually done.
- Start: catalog median $72,000 (basis: condition #2, ~40,000 mi).
- Mileage 38,400 vs ref 40,000 → 1% (6% / 10k mi).
- Model year 2008 vs gen midpoint 2006.5 → 3%.

The full forensic scope a proper appraisal of this class of car covers — 6 of 7 axes documented here, the rest in scope and marked pending.
Porsche factory build record (Kardex) on file, with a documented service history from new.
Engine and gearbox numbers cross-checked to the build record — matching numbers confirmed.
Panel fit and interior trim consistent with a preserved car; gaps and glass dates check out.
Paint-to-Sample (PTS) Riviera Blue — a documented factory special order, confirmed original by paint-gauge readings versus a later respray. PTS commands a premium over a standard colour.
Ownership chain documented from new, with no gaps in the history file.
997.1 Carrera S with the X51 Powerkit; original wheels, Sport seats and delete-options recorded.
Firewall: forensic findings inform authenticity, condition and risk — they never set the value. The estimate above comes solely from the Parclines valuation model.
No branded-title flags; no open safety recalls on file. Independent third-party signal — it informs risk, never the value.
You documented $18,400 in receipts (IMS/clutch, suspension refresh, PPI). The model attributes $6,200 of that to market value — the rest is maintenance the market expects, not a premium. The builder decides whether the work was worth it.
