2018 Porsche 911 4.0L Petrol · LE11 THY

A 2018 Porsche 911 carrying four consecutive PASS advisories-free MOTs, the latest issued on 10 May 2025, presents the textbook profile of a mechanically well-maintained performance car. Across all four recorded tests from 2022 through 2025 there is not a single advisory entry, which means the DVSA examiner found no component worn sufficiently to warrant even a note for future attention. For a rear-engined flat-six sports car that is now into its eighth year, the absence of brake disc corrosion advisories, suspension bush or coil spring notes, or any underbody corrosion remarks is a notably positive signal. The trajectory is one of complete stability with no deterioration between tests, suggesting the vehicle has been kept in roadworthy condition throughout the period it has been presented for testing. The mileage profile deserves careful consideration. At 24,486 miles over roughly eight years, this car has averaged only around 3,061 miles per year, which is exceptionally low even for a premium sports coupé and considerably below the typical 7,000 to 10,000 miles annual accumulation seen on everyday vehicles. This pattern is consistent with a second or weekend car that sees limited use, and the four MOTs have fallen at remarkably regular twelve-month intervals, implying the vehicle has remained on the road and in active use rather than being laid up in a garage for years at a time. Mechanically, low annual mileage on a flat-six Porsche of this generation means reduced wear on the major drivetrain components, but it does also place particular stress on items that degrade through lack of use rather than through distance covered, notably the battery, brake discs and calipers which can corrode and bind when sitting, and the tyre sidewalls which can suffer flat-spotting and cracking. For a prospective buyer, although the MOT record itself is clean, a careful physical inspection and test drive are still essential given the usage profile. On a road test, listen for any clonking or knocking from the front suspension over uneven surfaces, particularly from the lower wishbone bushes, and feel for vagueness or vibration through the steering rack under load, as these are common ageing points on the 991 platform. The brakes should be checked for a firm pedal with no excessive travel; any judder under light braking or a grinding sensation could indicate corroded front discs that have pitted from infrequent use rather than wear, and binding rear calipers can sometimes manifest as the car pulling to one side when first driven from cold. A visual inspection underneath should look for any oil seepage from the rear main seal, signs of coolant staining around the coolant pipes feeding the rear radiator, and any corrosion around the exhaust mounting points and undertrays, which can deteriorate from road debris and salt exposure even on low-mileage cars. Finally, given the likely pattern of short journeys and infrequent use, several non-MOT items warrant particular scrutiny before purchase. A 12V battery more than four or five years old on a car that is not driven daily is highly likely to be near the end of its service life, so check the date stamp and test cranking performance. Inspect all four tyres closely for sidewall cracking or flat spots, and verify they are within date, as perished rubber is a common finding on cars of this age even with plenty of tread remaining. The coolant, brake fluid and engine oil should be checked for age and condition, with any dark, degraded or low fluid levels suggesting the car may not have been serviced on a calendar basis. A compression test or at minimum a thorough diagnostic scan for any stored fault codes relating to the flat-six engine management system would be prudent, as low-mileage cars can develop issues with seals, injectors and age-related electrical faults that will not show on an MOT but can prove costly if overlooked.
