2003 Porsche 911 3.6L Petrol · KD52 ANV

The most recent MOT on 4 February 2026 was passed, with only an advisory noting rear brake disc wear and a minor fault on the nearside rear position lamp. All earlier tests from 2018 to 2025 also resulted in passes with no recorded defects, indicating a consistently stable maintenance record rather than any emerging trend of deterioration. The absence of recurring failures suggests that the vehicle has been kept in generally good order, although the rear‑disc advisory signals that the braking system will need attention in the near future. At 77 210 miles for a 23‑year‑old 2003 Porsche 911 the annualised mileage works out to roughly 3 350 miles per year, which is markedly below the typical usage for a sports car of this age. Such low utilisation often points to periods of limited driving or prolonged storage, which can be as much a concern as high mileage because components may have aged without the benefit of regular operating heat. The modest wear implied by the mileage means that many wear items such as tyres, brake pads and suspension bushings are likely to have a long service life remaining, but the calendar age of rubber and fluid‑based parts must still be considered. When you inspect the car, give particular focus to the rear brake discs: measure the remaining thickness against the manufacturer’s minimum, feel for any pulsation or shudder through the pedal at moderate speeds, and listen for a high‑pitched squeal that can indicate glazing. The rear position lamp should be tested for proper operation and its housing examined for corrosion or water ingress, as a faulty lamp can be a symptom of wiring harness deterioration. Because the car has spent many years with relatively low mileage, the tyres should be checked for sidewall cracking, dry‑rot and age‑related hardening; any tyre older than six years should be replaced regardless of tread depth. Verify the condition of the 12‑volt battery, preferably with a load test, and look for signs of sulphation or leaking that are common in long‑standing, low‑use vehicles. Beyond the brakes, a thorough visual and tactile inspection of the suspension is advisable: examine the front and rear coil‑spring mounts, anti‑roll bar links and rubber bushings for cracks, loss of elasticity or corrosion, especially around the rear sub‑frame where standing water can accelerate deterioration. Inspect the under‑carriage for rust on the chassis rails, exhaust hangers and brake lines, and confirm that the brake fluid has been changed within the last two years – a dark, moisture‑laden fluid will raise the risk of reduced braking performance. Finally, check that the engine oil, coolant and gearbox fluids are fresh and at correct levels, and request a full service history to confirm that the timing chain, valve‑clearance checks and any model‑specific items such as the rear‑main seal have been addressed at appropriate intervals.
