Our Verdict
This 2012 Mazda 6 diesel offers good recent MOT performance but carries some maintenance risks from past brake issues. A careful inspection is recommended before purchase.
Prioritize checking the brake system, particularly the parking brake mechanism and rear brake discs, which had serious defects in 2024. Verify service records to confirm repairs were completed. Negotiate based on the 2024 failure history, though subsequent MOTs show improvement. Insist on a pre-purchase inspection by a qualified mechanic familiar with Mazda's brake systems. Be cautious of potential hidden costs from older diesel components.
Diesel fuel economy for the 2.2L engine typically ranges between 40-50 mpg on the motorway, making running costs moderate. Tax band is £180 annually (2026 rates for diesel cars over 15 years old). Insurance group is likely mid-range (estimate £1,200-£1,500 annually). Major maintenance costs could include brake repairs, with rear disc replacements averaging £300-£500. Estimated annual running cost: £1,200-£1,500.
Focus on the parking brake system, rear brake discs (check for warping or thinning), and front brake calipers for binding. Inspect the brake fluid condition and look for signs of past repairs. Check the exhaust system for leaks or damage, common in older diesels. Verify the engine's oil consumption and check for DPF-related issues. Review service records for any brake system maintenance between 2024 and 2026.
The vehicle has a clean MOT history from 2024 to 2026 with no defects, but a 2024 failure highlighted significant brake system problems. Mileage of 64,486 miles is above average for a 14-year-old car, though the diesel engine remains reliable. No model-specific reliability data is available.
No aggregate MOT data available for the Mazda 6 model, making it difficult to assess broader reliability trends.
