Across all tests, the most frequently flagged areas are: Brakes (6 issues), Lighting (5 issues), Suspension (2 issues), Tyres (2 issues), Windscreen (1 issue). Repeated mentions in one area can indicate an ongoing pattern worth checking in person.
In total 12 advisory notices are recorded. Advisories flag items that passed but may need attention before the next test; they are not evidence of how well the vehicle has been serviced.
Recorded failure items include: “Offside Rear Registration plate lamp does not illuminate simultaneously with the position lamps (4.7.2 (a))”; “Nearside Rear Registration plate lamp does not illuminate simultaneously with the position lamps (4.7.2 (a))”; “Offside Front Position lamp not working (4.2.1 (a) (ii))”.

Expert automotive synthesis from historical MOT defect records and market benchmarks.
Our Verdict
Extreme caution. This high-mileage diesel shows significant signs of structural corrosion and deferred mechanical maintenance. While the engine may be robust, the consistent history of sub-frame rust and suspension wear suggests expensive repairs may soon be ahead.
The primary focus for this vehicle is a thorough structural inspection. Multiple MOT records have flagged 'sub-frame corroded' and 'under body rusty'. You must have a rust specialist inspect the chassis to determine if the corrosion is merely surface or structural, as a subframe replacement is a high-cost repair.
Mechanically, check the service history for the 1.6L diesel engine; at 137k miles, ensure the timing belt (if applicable to this specific variant) has been replaced. Given the recent failures of brake discs, pads, and ball joints, ask for invoices proving these have been replaced recently. Be prepared to negotiate down if these components are needing attention shortly after purchase.
The 1.6L diesel is relatively efficient for long motorway journeys, likely achieving 50-60 mpg if maintained well. It sits in a mid-range insurance group, and expect annual fuel costs of around £700-£900 based on average mileage.
Maintenance costs are likely higher than average due to the documented history of suspension wear and corrosion issues. You should budget more for annual repairs, placing the total annual running cost (fuel, tax, insurance, and maintenance) at approximately £1,100-£1,300.
Inspect the front and rear subframes and mounting points meticulously; the MOT history specifically mentions corrosion in 2024 and 2025. Look for flaking rust or holes. Also, check the front suspension arm bushes and track rod ends, as these have been flagged as worn or deteriorated in multiple tests.
Examine the braking system thoroughly. The vehicle had a 'dangerous' rating for rear brake pads and major failures for worn discs. Ensure the current pads and discs have significant life remaining. Additionally, test the wiper blades and all bulbs, as these have been recurring points of failure in the recent history.
This 2012 Mazda 3 has covered 137,633 miles, which is significantly above the UK average for its age. The MOT history reveals a concerning pattern of underbody corrosion, specifically regarding the subframe, and repeated failures of suspension components. While it recently passed its test, the frequency of major and dangerous failures regarding brakes, suspension, and wipers indicates a vehicle that has been reactive rather than proactive with maintenance.
The Mazda 3 of this era is generally considered reliable, but the diesel engines and chassis components can be prone to rust if not treated in UK winter climates.
