2023 Porsche 911 Turbo S S-A 3.7L Petrol · S 500

The most recent DVSA MOT test for this 2023 Porsche 911 Turbo S, conducted on 18 June 2026, resulted in a pass with two advisories recorded against the offside rear and nearside rear tyres. While a pass is naturally the desired outcome, the presence of these advisories signals that the rear tyres were approaching the legal tread limit and exhibited wear concentrated on the inner edge, an issue that can point towards the rear axle geometry being slightly off, suspension geometry wear, or simply an aggressive alignment set-up that promotes inner-edge loading on this particular rear-engined performance chassis. Given that only one MOT entry exists and it carries no advisories unrelated to the tyres, the immediate maintenance trend appears broadly stable, but the specific advisory warrants close scrutiny given the high performance and weight distribution characteristics of the Turbo S platform. The recorded mileage of 11,791 miles over an approximate three-year ownership period equates to around 3,930 miles annually, which is exceptionally low for a vehicle of any age, let alone a high-performance sports car. Such limited usage typically implies either a secondary leisure use profile or extended periods of standing, both of which carry their own mechanical implications. Prolonged standing can lead to brake disc corrosion, calliper seizure due to piston seal degradation, flat spots or sidewall cracking in the tyres, and 12 volt battery depletion, all issues that can manifest long before the odometer would normally suggest the need for attention. Conversely, the relatively low mileage means the major drivetrain consumables such as the clutch assembly, PDK transmission components, and internal engine wear items will have experienced minimal mechanical wear, provided the vehicle has been correctly serviced in line with its calendar-based schedule rather than purely its mileage-based intervals. For a prospective buyer, a thorough physical inspection should begin with a careful examination of all four tyres, paying particular attention to the inner shoulders where the recent advisories were flagged, as uneven inner-edge wear on the rear axle can sometimes indicate worn lower suspension links, degraded thrust arms, or a tracking issue that will necessitate a four-wheel alignment check and possibly component replacement. A test drive should be conducted with the vehicle cold to listen for any binding or grinding from the brake callipers, which commonly seize on low-mileage prestige cars, and the brakes should be tested at low speed to ensure smooth operation without judder. The underside of the vehicle and wheel arch liners should be inspected for any fluid weeping from the PDK transmission, rear differential, or axle seals, and the exhaust system should be checked for any signs of corrosion at the mounting points. Given the low annual mileage, it is also prudent to verify the full Porsche main dealer or specialist service history to ensure that the calendar-based servicing schedule has been strictly adhered to, as engine oil, brake fluid, coolant, and PDK transmission fluid all degrade with age regardless of mileage accumulation. The 12 volt battery should be load-tested, as repeated shallow discharge cycles from standing can permanently reduce its capacity, and the air conditioning system should be operated to confirm consistent cold output, as the compressor seals can deteriorate from infrequent use. Finally, a diagnostic read using a Porsche-specific tool such as a PIWIS tester is highly advisable to interrogate any logged fault codes within the chassis, transmission, and driver assistance control modules that would not form part of a standard MOT assessment but could reveal underlying electronic or sensor issues consistent with a complex, low-mileage modern performance vehicle.
