Our Verdict
A strong buy for those seeking a reliable mid-sized family saloon with exceptionally low mileage for its age. This vehicle presents a remarkably clean MOT record with no recorded failures in five years.
When inspecting this vehicle, prioritize the mileage history; since it has averaged only about 3,700 miles per year, check that rubber components and seals haven't perished from age rather than use. Ensure the service history is present to support the low mileage figures, as MOT records alone do not prove mechanical maintenance intervals.
Pay close attention to rust, which is a known trait for this generation of Mazda 6, specifically around the sills, wheel arches, and suspension mounting. Given the low usage, also check for any signs of fluid leaks that may have occurred if the car has sat stationary for extended periods.
The 1798cc petrol engine is relatively economical for a car of this size, falling into a mid-range insurance group. You can expect fuel economy around 30-35 MPG depending on driving conditions, though older engines may slightly impact these figures.
Maintenance costs for this model are generally affordable as parts are widely available for the older Mazda platform. Estimated annual running costs sit at approximately £900-£1,100, including fuel, tax, insurance, and routine servicing reserves.
While this specific vehicle has no MOT failures on record, the aggregate data for this model highlights highlights frequent issues with suspension arms and parking brake efficiency. You should physically inspect the front suspension bushings for play and test the handbrake to ensure it holds effectively on gradients.
Check the headlamp alignment and brightness, as this is a common reason for failure across the Mazda 6 fleet. Given the 2005 registration, a thorough check of the underbody for corrosion is vital, as MOT tests only detect structural rust once it becomes significant.
This 2005 Mazda 6 has covered just 78,976 miles over 21 years, which is significantly lower than the fleet average of 7,791 miles per annum. The vehicle has passed its last five MOT tests without a single defect, suggesting a consistent level of presentation. Combined with the practical 1.8L petrol engine, it represents a sensible and well-used option in the used-car market.
The Mazda 6 of this era is generally regarded as reliable-wise, though it is prone to exterior corrosion issues if not treated regularly.
