2006 Jaguar S-Type 4.2L Petrol · Y19 JAG

The most recent MOT, carried out on 21 November 2025, was passed but recorded a number of advisories concerning a minor central exhaust leak and damage to the prescribed areas of the front and rear sub‑frame mountings. While the vehicle has consistently passed its tests in recent years, the pattern of defects shows a clear shift from a clean record in 2020‑2022 to major structural corrosion warnings in late‑2023 and early‑2024, followed by only advisory items in the latest test. This suggests that the vehicle’s condition is stabilising after some remedial work, but the underlying trend of increasing corrosion remains a concern and warrants close scrutiny. With 72 607 miles logged on a 2006 model, the average annual mileage works out at roughly 3 600 mi per year, which is well below the typical UK usage of 8‑10 000 mi. Such low utilisation often points to long periods of inactivity or limited daily use, both of which can accelerate age‑related deterioration such as rust, battery sulphation and fluid breakdown, even though the wear on moving parts may be relatively light. Potential owners should be aware that the vehicle’s age, rather than mileage, is the dominant factor influencing component life. Prospective buyers must give particular attention to the sub‑frame and integral body structures that have been flagged for corrosion. Inspect the front and rear mounting points on both sides for any signs of rust penetration, flaking paint or compromised welds, and probe for flex or audible clunks when the car is driven over speed bumps or uneven surfaces. The off‑side front brake pipe, repeatedly noted as corroded and coated in grease, should be examined for thinning, leaks or signs of fluid contamination; a soft or spongy brake pedal, or any brake warning lights, would indicate that the pipe may need replacement. The minor central exhaust leak should be verified for audible hissing or a noticeable increase in cabin fumes, especially when the engine is under load, as this could affect both emissions compliance and occupant comfort. Given the vehicle’s age, a thorough visual and tactile check of the tyres is essential – confirm the DOT code to ensure they are not older than six years, look for sidewall cracking or perishing, and verify tread depth is within legal limits. Test the 12 V battery’s voltage and cranking performance, as long periods of storage can lead to reduced capacity. Examine coolant, brake and power‑steering fluids for colour change, sediment or low levels, and consider a full fluid change if service records are incomplete. Finally, verify that the headlamp aim has been corrected from the 2024 failure and that the alignment is satisfactory, as mis‑aimed lights can be a safety hazard and a recurring MOT issue. A comprehensive mechanical inspection covering these points will give a clear picture of the car’s current roadworthiness and any imminent maintenance that may be required.
