During the test drive, listen closely for a rhythmic 'ticking' or 'knocking' sound from the engine bay while at idle; this can be a helpful indicator to inspect the cylinder bores for any signs of scoring.
While driving at low speeds over bumps, listen for clunks or rattles from the suspension; these cars benefit from an inspection of the control arm bushings and drop links which can wear over time.
Before starting the car, check the service history for evidence of the IMS (Intermediate Shaft) bearing update or monitor, as owners often choose to proactively address this in higher-mileage examples.
Engage the clutch through the gears and check for a heavy pedal feel or slipping; a sticky or heavy clutch can be a helpful hint that the dual-mass flywheel and clutch assembly might eventually require some care.
Usually marks a time to ensure major belt replacements and comprehensive fluid flushes have been completed.
A common point where original suspension components and cooling system hoses are often inspected for signs of age-related degradation.
Generally the window where owners look closely at the condition of the water pump and potential air-oil separator seals.
Keep a consistent eye on oil levels, as these flat-six engines appreciate regular top-ups between scheduled services.
Ensure the cooling system is kept healthy by checking for any coolant residue or damp patches under the car after a drive.
Regularly clean the front radiator intakes, as leaves and road debris can accumulate and potentially affect cooling efficiency.
Maintain the convertible or hatch seals with a suitable rubber treatment to keep them supple and weather-tight.
Prioritize a pre-purchase inspection from an independent Porsche specialist familiar with the 987 platform to give you peace of mind.
Estimated repair costs if issues arise
In cars of this age, it is common to consider these as wear items. If you notice a small coolant leak or slight bearing noise, it is often wise to replace them together to ensure the cooling system remains reliable.
Depending on the car's driving history, you might eventually need to budget for a clutch replacement. Replacing the dual-mass flywheel at the same time is standard practice to maintain a smooth shift quality.
If the ride quality starts to feel a bit loose or noisy, it is quite common to budget for a refresh of the front and rear control arms to restore that characteristic sharp Porsche handling.
