2010 Mazda 3 1.6L Diesel · SA10 SYG

This Mazda 3 last passed its MOT on 14 September 2021, with no defects recorded at that time. The absence of any subsequent tests—particularly none in the intervening five years—raises immediate concerns. A vehicle of this age and mileage should have undergone at least one further MOT by now, given the UK’s biennial testing cycle. The lack of any recorded failures or advisories in 2021 suggests the car was in a passable condition at that point, but the prolonged gap without retesting implies either neglect or deliberate avoidance of inspection. Buyers should treat this as a red flag, as critical components—such as suspension bushes, coil springs, and brake calipers—could have deteriorated significantly without oversight. The recorded mileage of 139,583 miles over approximately 16 years equates to an average of around 8,700 miles annually, which is typical for a car of this age. However, the sparse MOT history makes it impossible to correlate mileage with maintenance consistency. Without intermediate tests, there’s no way to verify whether the vehicle was driven regularly or stored for extended periods, which could accelerate wear on fluids, tyres, or suspension. The absence of any advisories in 2021 does not preclude hidden issues—corrosion, for instance, or gradual degradation of drivetrain components—especially given the car’s age. A buyer should treat the mileage figure as a starting point rather than a definitive indicator of care. Given the lack of recent MOT data, a thorough pre-purchase inspection is essential. Focus on the suspension, where rubber bushes and coil springs are likely candidates for failure after 16 years. Check for binding rear brakes, which are common in this model as wear progresses. Examine the chassis for structural rust, particularly around the wheel arches and sills, as corrosion can compromise structural integrity. The brakes should be inspected for uneven wear or glazing, and the exhaust system should be checked for leaks or excessive corrosion, which could indicate poor maintenance. Tyres, despite not being flagged in 2021, may now be worn beyond legal limits, especially if the car has been driven inconsistently. Prioritise these areas to assess whether the vehicle remains roadworthy or if it requires costly repairs.
