Pre-purchase screen · photos-only
The check you run

The report
Scorecard first. Evidence underneath.
Every finding is tied to the exact photo that shows it. Anything the photos can't show is marked needs-PPI — never guessed.
2006 Porsche 911 Carrera S
Rear main seal seepage
Oil film visible on the bell-housing in the underbody shot. Common on M97 — budget to do it with the next clutch.
A$1.1–1.7k
IMS bearing — pre-2009, single-row
Derived from VIN + year, not the photos. No upgrade invoice in the history shown. Address at next clutch or get it confirmed.
A$3.5–5.5k
Coolant weep at radiator / front pipes
Staining on the nearside front in the bumper-off-angle photo. Cheap if caught early, tedious if ignored.
A$0.8–1.5k
Bore scoring, clutch %, compression
Not visible in any photo. We won't guess. Take a cold-start video and these three checks to your inspector.
9 stamps reconciled · 1 gap 2014–2016 (~15,000 km unaccounted) · last major 6,800 km ago.
“Has the IMS been upgraded — invoice?” · “Reason for the '14–'16 gap?” · “Cold-start video?”
