1992 Porsche 911 3.6L Petrol · B2 EEE

The most recent MOT test, conducted on 2026-04-23, resulted in a clean pass with no recorded defects, marking a positive deviation from the vehicle’s previous MOT history. However, the prior test on 2026-04-22 revealed several major failures, particularly concerning the rear anti-roll bar linkage bushes on both sides, which were found to be excessively worn. These failures suggest a pattern of mechanical degradation in the suspension system, likely indicating ongoing wear and potential long-term structural compromise to the anti-roll bar linkages. While the intervening years have seen no further MOT failures, the presence of these recurring issues—particularly in a high-stress component like the anti-roll bars—demands careful attention to their condition and the broader suspension integrity, as repeated wear can lead to premature failure of associated components, such as coil springs or strut mounts. The recorded mileage of 48,719 miles for a vehicle aged approximately 34 years represents an unusually low annual usage rate of around 1,433 miles per year, which is far below the typical wear rates expected for such an older Porsche. This low mileage could imply either infrequent driving or extended periods of the vehicle being stationary, both of which can accelerate specific forms of deterioration. Standing for prolonged periods can cause brake discs to corrode, leading to binding calipers or uneven braking performance, while fluid degradation—particularly in hydraulic systems—can accelerate without regular use. Additionally, the lack of recent mileage accumulation might mask underlying issues that only manifest under dynamic conditions, such as suspension clunks from worn suspension bushes or exhaust emissions problems from carbon buildup in the catalytic converter. Given the vehicle’s age and the recurring MOT failures, particularly the rear anti-roll bar linkage bushes, the prospective buyer should conduct a thorough inspection of the suspension system. Focus on the rear anti-roll bars themselves, checking for any signs of excessive play, cracks, or detachment from the linkages. Listen for any unusual clunking noises during cornering or braking, which may indicate misalignment or binding. The test drive should also include a slow-speed drive to assess brake performance, particularly on the rear wheels, where corrosion or binding calipers could cause uneven stopping or a spongy pedal feel. Additionally, visually inspect the rear suspension components for any signs of rust or wear, as the low mileage may have allowed moisture to penetrate and accelerate corrosion in stationary areas. For the buyer’s practical inspection, examine the tyres for signs of sidewall perishing or cracking, which can occur even with low mileage due to prolonged exposure to environmental elements. Check the 12V battery for signs of corrosion on terminals or a sluggish cranking performance, as older batteries in stationary vehicles can degrade faster. Inspect the brake discs for corrosion, warping, or uneven wear, particularly on the rear, where standing can exacerbate issues. Verify that all fluids—oil, coolant, brake fluid, and transmission fluid—are at the correct levels and show no signs of contamination or degradation, as fluid changes should be performed at regular intervals, even if the vehicle hasn’t been driven extensively. Lastly, check the exhaust system for leaks or excessive backpressure, which could indicate catalytic converter failure or flex pipe damage, both of which are critical to emissions compliance and safety. If the vehicle has been stationary for extended periods, consider a thorough fluid flush and a check of the fuel system for moisture ingress, which can lead to corrosion in the fuel lines or injectors.
