2001 Porsche Boxster 2.7L Petrol · STR 11K

A chronic pattern of advisories affecting the rear anti-roll bar bushes and brake pipes, combined with evidence of tyre management issues, defines the mechanical trajectory of this 2001 Porsche Boxster, even though the most recent test on 11 July 2026 returned a clean pass with no defects recorded. The 2025 advisory set flagged wear to both rear anti-roll bar pins or bushes and corrosion on both rear brake pipes, alongside an oil leak described as not excessive, suggesting early-stage deterioration in the underbody and suspension components typical of a 25-year-old sports car. The 2024 results are more concerning: a fail issued on 3 July 2024 cited dangerously low rear tyre tread depth below 1.6mm on both sides, with the front tyres simultaneously flagged for cracking and perishing, indicating a pattern of prolonged tyre neglect prior to that test. A follow-up pass later that month addressed the dangerous items but retained the front tyre cracking advisories, and the headlamp aim test failure raises a minor question over the lighting system's condition that should be physically inspected. With 126,137 miles accumulated over 25 years, this Boxster averages roughly 5,045 miles annually, which is notably low for the model and indicates extended periods of either light use or inactivity. The gap between the 2022 test and the 2024 test suggests at least one missed MOT cycle, consistent with a vehicle that may have been laid up or used very sparingly during that interval. While low annual mileage reduces wear on major drivetrain components, it elevates the risk of standing-start deterioration in rubber seals, brake calipers, and flexible hoses, which aligns with the observed anti-roll bar bush wear and oil leak advisories recorded on the rear axle area. Buyers should treat the mileage as a double-edged figure: the engine and gearbox are likely to have covered modest distances, but the chassis and underbody components have nonetheless aged through calendar years rather than use. On a physical inspection, focus particular attention on the rear anti-roll bar mounting points, pressing firmly on the rear quarter while watching for vertical play at the bar ends, and listen for clonking noises over uneven surfaces which would confirm the worn bushes flagged in 2025. The rear brake pipes should be examined closely for advanced corrosion, pitting, or active rust weeping, especially at the unions near the rear axle and along the underfloor routing, as the 2025 advisory noted corrosion covered in grease, which often masks deeper degradation. Inspect the underbody, subframe, and rear suspension arms for any structural corrosion that has not yet progressed to advisory level, and look for oil residue around the engine sump, cam chain covers, and rear main seal area to gauge the severity of the noted oil leak. During the test drive, listen for any rear suspension knocking or imprecise handling through corners, as worn anti-roll bar components will allow noticeable body roll and looseness. Check the brake pedal for a spongy feel or excessive travel, which could indicate the corroded rear brake pipes are close to requiring renewal, and verify the handbrake holds firmly on a slope given the rear caliper design common to this model. Tyres should be examined for even tread wear across both axles and any sidewall cracking, as the history of rapid tread depletion on the rears and front tyre perishing suggests the car may have stood on ageing rubber for prolonged periods. Finally, confirm that all headlamps produce a sharp, level beam pattern, since the 2024 inability to test headlamp aim could indicate a levelling motor or adjuster fault that warrants rectification before the next test.
