2006 General Motors Cadillac 2.0L Petrol · FN06 EYM

The most recent MOT test on 28 August 2025 resulted in a pass, with only a single advisory noted for a nail in the nearside front tyre. Looking back over the last five years, the maintenance trend for this Cadillac appears somewhat reactive, characterized by periodic failures for wear-and-tear items followed by successful retests. The vehicle failed in September 2024 due to inadequate parking brake effort on the nearside rear, and previously in September 2021 due to an excessively worn offside front anti-roll bar linkage ball joint. While the owner has consistently addressed these major defects to secure a pass, the recurring presence of advisories for fluid seeps and uneven tyre wear indicates that maintenance is often deferred until absolutely necessary for the annual test. With a recorded mileage of 106,423 miles over approximately twenty years, this vehicle has covered an average of roughly 5,321 miles per year, which is notably low for a large-displacement American import. While low annual mileage is superficially attractive, it frequently indicates extended periods of inactivity. For a vehicle of this age and complexity, prolonged standing can accelerate the deterioration of rubber components, such as suspension bushes, engine mounts, and auxiliary belts, which dry out and perish without regular use and heat cycles. Furthermore, low mileage can mask underlying mechanical degradation, such as internal engine sludge from short trips where the oil never reached optimum operating temperature, or moisture accumulation in the exhaust system leading to premature internal corrosion. A prospective buyer must pay close attention to several historical mechanical issues during a physical inspection and test drive. The power steering system has a history of slight seepage from both the pump in 2022 and the steering rack pinion in 2023. Although these did not reappear as advisories in the most recent tests, the steering rack and pump should be closely inspected for active fluid leaks, and the hydraulic fluid level must be verified. On the test drive, listen for any whining or groaning noises from the power steering pump when turning the wheel from lock to lock, and feel for any tight spots or play in the steering. Additionally, the historical advisory for corrosion on the offside front brake hose ferrule warrants a visual check of all flexible brake hoses for cracking, swelling, or advanced corrosion on the metal end fittings, as this directly impacts hydraulic braking integrity. The recurring advisory for a product on the headlamp lenses suggests UV degradation or aftermarket tinting films, which can severely impair night-time visibility and should be checked for cloudiness or peeling. The MOT history also highlights a pattern of uneven tyre wear, specifically the nearside front tyre being worn bald on its inner edge in 2021. This symptom points directly to tracking misalignment or worn front suspension geometry components, such as control arm bushes or ball joints. During the test drive, assess if the vehicle pulls to one side on a flat road or if there is any steering wheel shimmy at speed. The failure of the parking brake in 2024 suggests that the rear brake calipers, cables, or shoe-in-disc mechanisms are prone to binding or seizing, a common issue on vehicles that sit idle. Test the handbrake operation on a steep incline to ensure it holds firmly and releases cleanly without dragging. Given the vehicle's age, a comprehensive inspection of the underbody is vital to check for structural corrosion, particularly around the subframes and sills, alongside verifying the age of the tyres by their DOT date codes to ensure they have not perished from age despite having adequate tread.
