2005 Porsche Boxster 2.7L Petrol · IJI 800

This 2005 Porsche Boxster failed its most recent MOT on 10 June 2026 at 28,241 miles, and the maintenance trend is clearly worsening. The tester flagged a fractured or broken offside rear coil spring, an insecure nearside rear coil spring, a broken nearside rear exhaust hanger, and slight corrosion to the offside rear brake hose ferrule. A broken coil spring is a serious structural failure that directly compromises suspension geometry and handling stability. The fact that both rear springs are now compromised, combined with a corroding brake hose, suggests the car has been neglected in recent years. The mileage pattern tells a very specific story. Between the clean pass on 28 March 2013 at 27,565 miles and the failed tests in April and May 2021 at 28,226 miles, the car covered only 661 miles in over eight years. It then remained at exactly 28,226 miles for both 2021 tests and has advanced just 15 miles by the June 2026 failure. This is exceptionally low annual use of roughly 1,345 miles over the vehicle's 21-year life. Such prolonged static storage is often more damaging than regular driving, as suspension components seize, brake calipers stick, tyres flat-spot, and rubber hoses and bushes perish from age rather than mileage. The recurring rear brake disc advisories from 2021, now escalating to a corroded brake hose ferrule in 2026, indicate the rear braking system has suffered from long periods of inactivity. A binding caliper or collapsed hose is a likely consequence. The dual rear coil spring failures are particularly concerning. These components do not fracture spontaneously on a car that has covered barely 28,000 miles unless the vehicle has been stored with suspension loaded on uneven ground, driven over severe impacts, or simply suffered from age-related metal fatigue exacerbated by corrosion. A buyer must physically inspect the entire underside for corrosion to suspension mounting points, subframe rails, and sills before committing. The rear brake hoses, calipers, and discs need close examination for seizure or uneven wear. Both rear coil springs require immediate replacement, and the front springs should be checked for similar fatigue. The exhaust hanger failure points to broader exhaust system corrosion. Tyres must be checked for age-related cracking, as original or near-original rubber is almost certain at this mileage profile. This record reflects a car that has stood still for long periods and now needs thorough mechanical recommissioning.
