2004 PORSCHE BOXSTER2.7L PETROL

The most recent MOT, conducted on 13 August 2025 at 37,712 miles, resulted in a pass, but the record reveals a clear and worsening trend in rear braking system deterioration. The tester flagged both rear inner brake discs as worn, pitted, scored, and corroded. This marks a progression from the previous year's test on 16 August 2024 at 37,016 miles, where the same issue was identified on both rear discs, alongside deteriorated rear exhaust clamps and a perished fuel cap seal. The recurrence of pitted and scored rear discs across consecutive years, now with added corrosion, indicates a persistent problem that is not being rectified, only managed to a passable standard. The maintenance trend is therefore worsening, pointing to a pattern of minimal, reactive repairs rather than proactive component replacement. The mileage profile is exceptionally low for a 2004 vehicle. The recorded 37,712 miles equates to an average of just 1,714 miles per year over 22 years. The MOT history confirms this sparse usage, with only 3,365 miles covered between the August 2022 test at 34,347 miles and the August 2025 test at 37,712 miles. Such low annual mileage suggests long periods of inactivity, which directly explains the recurring corrosion on the brake discs and the perished rubber seals. Components are deteriorating from age and lack of use rather than from wear through regular driving. A buyer must physically inspect the rear braking system with extreme caution. The repeated advisories for pitted, scored, and corroded rear discs suggest the calipers may be sticking or the handbrake mechanism on this rear-engined car is seizing, a common issue that accelerates disc corrosion during periods of standing. The condition of the rear subframe and suspension mounting points should be thoroughly checked for structural corrosion, as a 22-year-old, low-mileage Porsche stored for long periods is highly susceptible to this form of decay. The deteriorated rear exhaust clamps noted in 2024 also warrant close inspection for exhaust gas leaks and corrosion along the system's seams. Beyond the flagged items, a pre-purchase inspection must focus on the condition of all rubber bushes, tyre date codes, and the operation of the convertible roof mechanism. The perished fuel cap seal, a minor issue, is symptomatic of aged rubber components throughout the vehicle. Given the pattern of recurring brake defects and the corrosion risks inherent in a low-mileage, ageing sports car, a specialist Porsche inspection is strongly advised before purchase.
