Everything you need to know before buying a used Porsche in Adelaide. What a PPI covers, model-specific risks, and why $650 is the best money you will spend.
A Rennen PPI is a comprehensive assessment of a used Porsche's mechanical condition, service history, and known model-specific risks. It is not a superficial visual check — it is a systematic inspection carried out by a specialist who knows every Porsche model's failure patterns, service requirements, and red flags.
Every Rennen PPI includes: PIWIS dealer-level diagnostic scan of all vehicle modules, road test assessment, underbody inspection on a hoist, brake inspection, tyre condition and wear pattern assessment, fluid condition checks, cooling system inspection, evidence of accident repair, service history assessment, and a written report covering all findings with recommended actions and estimated costs.
The PIWIS scan is particularly valuable — it reads stored fault codes across every module (engine, transmission, ABS, airbag, suspension, body control) that may not be showing as active warning lights. A car that appears to be fault-free may have dozens of stored faults that indicate ongoing issues or previous damage.
Porsche Macan: PTM fluid history, coolant pipe condition (2014-2018), PDK service history, suspension wear.
Porsche 996 / 997.1 911: IMS bearing history, RMS leak evidence, bore scoring on high-mileage cars, coolant condition.
Porsche Cayenne: air suspension condition, V8 bore scoring risk, coolant pipe condition, transfer case fluid history.
Porsche 986 / 987 Boxster: IMS bearing history, AOS condition, roof drain condition, cooling system.
Air-cooled 911 (930/964/993): engine number matching, case condition, heat exchanger integrity, valve clearance history.
The right time to book a PPI is before you make an offer or pay a deposit — not after. Once money has changed hands, the negotiating leverage from a PPI finding is gone. Rennen recommends booking the inspection as a condition of your offer: make the purchase subject to a satisfactory independent inspection, then proceed with the PPI before committing.
Private sales in particular benefit from a PPI. The seller has no warranty obligation and may genuinely not know the car's full history. A PIWIS scan and physical inspection by a Porsche specialist gives the buyer confidence — or identifies issues that either kill the deal or create a negotiating position on price.
A $650 PPI has saved Rennen clients from purchases with hidden transfer case failure, coolant system damage, accident repairs concealed by a respray, and IMS bearing failure about to happen. It is consistently the best money spent in a Porsche purchase.
The car can be brought to Rennen at 20-22 Commercial Street, Marleston, or Rennen can arrange for the inspection at a dealer or private address in the Adelaide metropolitan area. Call 0412 888 441 to book.

A Porsche pre-purchase inspection at Rennen starts from $650 + GST and includes PIWIS diagnostics and a written report.
Before you make an offer or pay a deposit. Make the purchase conditional on a satisfactory independent inspection. A PPI after money has been paid loses the negotiating leverage.
