1987 RS Cosworth 500 Sierra 2.0L Petrol · E331 JYP

The most recent DVSA MOT, carried out on 7 June 2022, was passed with no recorded defects or advisories. With only a single MOT entry in the vehicle’s history, it is not possible to identify a clear trend in maintenance quality, but the absence of any failures at that test suggests that, at least at the time of inspection, the fundamental safety items were serviceable. In the absence of earlier records, a prospective buyer should treat this as a snapshot rather than evidence of a long‑term maintenance regime. The odometer reads 40,711 mi on a vehicle that is now 39 years old, giving an average of roughly 1,040 mi per annum. This is considerably below the typical usage pattern for a car of this vintage and points to either very light, occasional driving or extended periods of storage. Low annual mileage can be advantageous in terms of reduced wear on engine internals, clutch and transmission components, but it also raises the likelihood of age‑related deterioration such as rubber hardening, corrosion of metal parts that have been idle, and potential battery depletion. Any sudden spikes in mileage that are not reflected in the recorded figure could indicate unlogged use and should be clarified with the seller. Given the low mileage and the age of the 1987 RS Cosworth Sierra, the buyer should focus on time‑based degradation. Inspect the tyre sidewalls for cracking, dry rot or any signs of perishing, as rubber ages even when the tread depth appears adequate. Examine the wheel rims for corrosion, especially around the spokes and mounting bolts, and check that the tyre pressure holds when inflated. The 12‑volt lead‑acid battery is likely to be well beyond its service life; a load test or a voltage check after a short idle will reveal its condition, and replacement may be required even if the car starts. Look for signs of rust on the chassis, particularly in the wheel arches, sills and under‑body, and verify that any rust is surface‑level rather than structural. A thorough mechanical inspection should include the suspension and steering components, as ageing rubber bushings, worn ball joints and possible seized coil springs can develop stiffness or clunking noises when the car is driven over bumps. Inspect the brake system for disc rust, especially if the vehicle has been stationary for long periods; surface rust can cause a pulsating feel or uneven pad wear, and caliper pistons may be sticky, leading to brake drag. Verify that all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – are topped up and free of sludge; fluids over ten years old typically need to be flushed and replaced. Finally, request any service book entries or receipts that confirm regular oil changes, timing belt or chain maintenance, and any major component replacements, as these records will give the most reliable indication of how the car has been cared for despite the sparse MOT history.
