The most recent DVSA MOT test on 2026-03-31 resulted in a passing outcome with a single advisory concerning the offside front brake pads exhibiting significant wear, classified as being reduced to just 1.1 millimetres of friction material remaining. This advisory, which has not been repeated in prior MOTs, suggests that the brake system on that side has been underutilised or subjected to uneven braking patterns, potentially due to prolonged idling or one-sided driving habits. The absence of failures or further advisories over the preceding four years indicates a generally stable maintenance record, though the single advisory warrants closer attention to prevent potential future issues, such as reduced braking effectiveness or premature pad replacement. The vehicle’s recorded mileage of 27,488 miles over approximately 12 years represents an annual usage rate of around 2,291 miles, which is notably lower than would be expected for a vehicle of this age and model. Such low mileage can often reflect periods of extended stationary use, particularly if the car was kept in a garage or used primarily for short commutes or leisure trips. However, this pattern may also imply that certain components, especially those exposed to prolonged inactivity—such as the brake systems, suspension, and fluids—have not undergone the typical wear and tear associated with higher mileage. The low usage rate could contribute to issues like corrosion from standing fluids, particularly in the brake master cylinder, caliper seals, or suspension bushings, which may require inspection to avoid dry friction or binding during operation. Given the clean MOT history aside from the single advisory on the offside front brake pads, the buyer should prioritise a thorough inspection of the braking system to confirm the advisory’s validity and ensure no underlying issues exist, such as warped discs, seized calipers, or fluid leaks from the master cylinder or wheel cylinders. During a test drive, listen for unusual noises from the front brakes, particularly when applying the pedal—any grinding, squeaking, or excessive pedal travel could indicate further wear or mechanical failure. Additionally, check for uneven tyre wear patterns, which might suggest one-sided braking or suspension misalignment. The offside front brake pads should be replaced as soon as possible, ideally within the next 10,000 to 15,000 miles, to maintain safe stopping performance and prevent damage to the discs. Beyond the braking system, the buyer should conduct a comprehensive physical inspection of the vehicle’s exterior and undercarriage. Given the low mileage, focus on signs of age-related degradation, such as the perishing or cracking of the tyre sidewalls, which can compromise structural integrity and tread depth over time. Inspect the 12-volt battery for corrosion around terminals, a common issue in stationary vehicles, and test its charge capacity by attempting to start the engine or using a multimeter. Fluid levels should be checked—particularly the brake fluid, coolant, and engine oil—ensuring they are topped up and free from contamination, as fluids degrade over time even with low mileage. Finally, verify that the service book or maintenance records have been updated, particularly for time-based services like the brake fluid flush, which should have been conducted within the last two years to prevent moisture ingress and fluid breakdown. If the service history is incomplete, schedule a professional inspection to address any outstanding or overdue maintenance tasks.
