Our Verdict
A strong purchase candidate for those se
When inspecting this vehicle, pay close attention to the offside front wheel bearing, as this was a recorded failure in July 2026. Ensure that the repair has been documented and that the slight play noted in the MOT has been fully rectified. You should also verify that the headlamp aim has been correctly calibrated following the recent failure.
Given the high-performance nature of the 3996cc engine, request evidence of specialist service intervals rather than relying solely on the MOT history. While the MOT records are clean for several years, they do not confirm the mechanical upkeep required for a vehicle of this specification. Check for any signs of uneven tyre wear which could relate to the wheel bearing issue or suspension geometry.
Running a 4.0-litre Porsche 911 involves significant costs. Fuel economy will be relatively low compared to standard road cars, and the high-performance petrol engine will place it in a higher insurance group and tax band.
Maintenance costs for this model are typically higher than average, particularly for tyres and braking components. While the MOT history shows no major exhaust or brake pipe failures—which are common for this model aggregate—you should budget for premium parts and specialist labour. An estimated annual running cost would be roughly £3,500-£5,000 depending on mileage and driving style.
The most critical item to inspect is the offside front wheel bearing, which was flagged with 'slight play' during the July 2026 MOT failure. Listen for any humming or grinding noises from the front end during a test drive. You should also check the nearside rear tyre to ensure the nail reported in the 2026 MOT has been replaced with a high-quality tyre.
Additionally, check the headlight alignment to ensure the 'headlamp aim too high' issue from the recent failure has been resolved. Finally, despite the clean MOT record between 2023 and 2025, inspect the underside for any signs of fluid leaks or wear that might not have triggered an MOT advisory but are relevant to a high-performance vehicle.
This 2018 Porsche 911, finished in green, shows significantly lower-than-average usage for its age. With 27,268 miles recorded in its most recent July 2026 MOT, it has been driven much less than the model aggregate average of 2,160 miles per year. While the most recent test resulted in a failure due to wheel bearing play and headlamp aim, the previous three years of testing showed no defects recorded.
The Porsche 911 shows a high average MOT pass rate of 90.8% across 56,325 analysed vehicles, though common failure points include exhaust, headlamp, and brake pipes.
