Our database tracks 4 specific mechanical faults and recurring failure patterns identified across UK MOT testing stations for this generation.
MOT Roadworthiness: Below Average
This rating reflects historical MOT pass rates and recurring advisory wear patterns from official DVSA test logs. Note that roadworthiness does not verify outstanding finance, insurance write-offs, or stolen records.

Our Verdict
Approach with caution and budget for immediate maintenance, as this 2005 Porsche 911 has a history of repeated MOT failures in 2024 and several outstanding wear items. It is a usable example with below-average mileage, but the recent test records show it needed multiple attempts to pass.
Given the 2024 MOT failures for headlamp aim, inoperative lamps, and corroded brake pipes, insist on evidence that all noted defects were properly repaired rather than temporarily patched. The September 2024 failure listed Offside Front headlamps not working on dipped or main beam and a corroded brake pipe, so confirm the brake pipes and front lighting have been professionally restored. A full service history is essential on a 3.6-litre 911 of this age; without it, walk away or negotiate hard.
As a 3600cc petrol Porsche, this 911 will incur high fuel costs, with real-world economy likely in the low 20s mpg; annual road tax for a 2005 petrol vehicle of this size will be in the higher bands. Insurance will be expensive due to the performance class and 20-year-old sports car status, and specialist maintenance on a 911 is costly — expect routine servicing to run into hundreds of pounds. Estimated annual running costs including fuel, tax, insurance, and typical maintenance are likely to fall between £4,000 and £6,000.
The MOT history shows recurring issues: the fuel cap rubber seal was noted as splitting or perished from 2024 into 2025, so check for fuel vapour smell and replace the seal. Rear tyres were worn close to the legal limit on both sides in 2025 and rear shock absorbers showed light oil misting across multiple tests — inspect tyre tread depth and shock condition closely. The Nearside Rear position lamp was partially inoperative in both 2024 and 2025, and front suspension ball joints had slight play in 2024, so verify all lamps work and have the front suspension checked for wear.
This blue 2005 Porsche 911 (MX55AGZ) recorded 106,627 miles at its October 2025 MOT, which is below typical mileage for a 20-year-old sports car. The MOT history shows clean passes in 2023 and 2025 but two failures in September and October 2024, with a wide range of lighting, tyre, and suspension faults. The most recent pass still notes an oil leak, worn rear tyres, rear shock misting, and a partial rear position lamp failure, so cosmetic and mechanical wear is present.
No aggregate MOT reliability data is available for the Porsche 911, so assessment is limited to this vehicle's individual history.

Historical MOT pass rates and DVLA records for 2005 model year cars.
- Bore Scoring (Gen 1)Serious
The Lokasil/Alusil cylinder liners degrade, causing the piston to score the walls. Eventually requires a full rebuild.
- IMS Bearing (997.1)Serious
While the 997.1 uses a larger bearing than the 996, early 2005 models still use the smaller bearing. Later 997.1 cars use a larger, more robust bearing but failure is still possible.
- Cracked Ignition Coil PacksModerate
The coil packs on 997 engines are prone to cracking and failing, causing misfires. A relatively inexpensive fix but common across all variants.
