Our Verdict
Approach this 2015 Mazda 6 diesel with caution and budget for immediate tyre and brake maintenance. The MOT history shows repeated advisories and two failures linked to tyres and brakes, though it currently holds a valid pass.
When viewing GM15AVT, request full service history to confirm the 2.2-litre diesel engine has had timely oil and timing chain intervals, as Mazda's diesel units are sensitive to neglect. Use the 2025 failure for four tyre defects (two below legal limit or cords exposed) as leverage to negotiate at least £300-£400 off, reflecting the cost of a full set of tyres and brake pads noted as wearing thin in 2026. Ask the seller why plastic underbody covers obscured inspection in 2025 and ensure no corrosion or leaks were hidden beneath them.
The 2191cc diesel typically returns 50-60 mpg, placing it in a lower Benefit-in-Kind and road tax band than petrol equivalents, though pre-2017 diesels may incur ULEZ charges outside compliant zones. Insurance for a 2015 Mazda 6 diesel is generally Group 18-22, costing roughly £400-£550 annually for a clean record. Estimated annual running cost including fuel, tax, insurance and maintenance is £1,100-£1,400 given the mileage and needed consumables.
Inspect all four tyres closely: the 2025 MOT failed on Nearside Front below 1.6mm, Offside Front cords exposed, and Offside Rear cut to cords, while the 2026 pass notes Nearside Rear worn on edge — confirm replacements are recent and even. Check front and rear brake pad thickness, as advisories for thinning pads appear in 2023, 2025 and 2026, and test the Offside Front upper anti-roll bar ball joint with slight play flagged in 2026 for excess movement. Verify the windscreen wipers clear effectively after the 2023 failure and remove underbody covers to examine for fluid leaks or corrosion.
This red 2015 Mazda 6 diesel (GM15AVT) has covered 102,683 miles as of its May 2026 MOT, which is in line with typical use for an 11-year-old car. The history includes two MOT failures in 2023 and 2025, both caused by tyre defects and minor wiper or brake issues, but all were addressed and the vehicle passed subsequently. Current advisories flag worn tyres and thinning brake pads front and rear, indicating upkeep has been reactive rather than preventative. Without model aggregate reliability data, assessment rests solely on this vehicle's own record.
No aggregate MOT reliability data is available for the Mazda 6, so this assessment is based only on the individual history of GM15AVT.
