2007 Porsche Cayman 3.4L Petrol · YC57 JBY

The 2007 Cayman passed its most recent MOT on 14 October 2025 at 83,938 miles, but the overall maintenance trend is one of gradual, unresolved deterioration rather than active repair. Corroded brake pipes and worn, pitted brake discs appear as persistent advisories in every single test from October 2020 through October 2025. The tester flagged both front and rear brake pipes corroded and covered in grease or other material in the 2025 test, mirroring identical findings from 2024, 2023, and 2022. Front brake discs were noted as worn, pitted, or scored in 2025, 2024, 2023, and 2022, with rear discs similarly flagged in 2025, 2022, and 2020. These are not new defects. They represent a five-year pattern of advisories carried forward without remedial work, suggesting the previous owner tolerated surface-level brake component wear and corrosion rather than addressing the underlying causes. The vehicle remains roadworthy by MOT standards, but the cumulative neglect of brake system upkeep is a serious concern for a performance car. The mileage profile tells a different story. At 83,938 miles over approximately 19 years, the Cayman has averaged roughly 4,418 miles per year, which is exceptionally low. The annual intervals between MOTs reinforce this: 75,832 miles in October 2020, 76,187 in October 2022, 79,127 in October 2023, 81,916 in October 2024, and 83,938 in October 2025. That is a gain of just 8,106 miles over five years, or about 1,621 miles annually in the most recent period. Long periods of standing are a known risk for brake corrosion, tyre flat-spotting, and seal degradation, and the persistent brake pipe corrosion advisories are entirely consistent with a car that sits unused for extended stretches. The gap between October 2020 and October 2022 is notable, with only 355 miles added in two years, reinforcing the likelihood of prolonged inactivity. A buyer should inspect the brake system with particular care. The repeated advisories for corroded metal brake pipes, especially at the flexi-hose-to-caliper connections, warrant a close visual check for pitting, weeping, or bulging under pressure. Grease contamination on brake lines is unusual and may indicate prior botched repairs or an attempt to mask deterioration. Both front and rear brake discs have been flagged as pitted and scored for years, meaning the pads may also be contaminated or unevenly worn. The offside front service brake fluctuation noted in 2024 could point to a sticking caliper or uneven disc thickness, which should be verified with a road test and dial indicator measurement. Tyre condition has been borderline in multiple years, with tread depths recorded at 3.0mm in 2022 and cuts noted on sidewalls, so any remaining original or aged rubber should be treated as suspect regardless of remaining tread. Beyond the brakes, the cracked registration plate appearing in 2023 and 2024 is minor but symptomatic of a car where small cosmetic and consumable items were left unattended. The low annual mileage and persistent corrosion advisories together suggest a vehicle that was lightly driven and poorly maintained during its standing periods. A pre-purchase inspection should include a thorough underside examination for structural corrosion, especially around subframes, sills, and suspension mounting points, as well as a full brake fluid flush and system pressure test. The Cayman's mechanical condition cannot be fully assessed from MOT records alone, but the paper trail points to a car that needs attentive mechanical recommissioning before it can be considered reliably roadworthy for spirited driving.
