Our Verdict
Proceed with caution. While this 2006 BM
Focus on the evidence of corrosion. The July 2026 failure specifically noted a corroded offside rear brake pipe; you should check other underbody components for similar rust. Ensure there is documented proof that the anti-roll bar ball joints and front tyres were replaced as required by the MOT.
Given the 2497cc petrol engine and the vehicle's age, request a comprehensive service history to see how the engine has been managed over 147,000 miles. Negotiate the price based on the likelihood of further wear-and-tear items emerging, as this vehicle is now two decades old.
The 2.5L petrol engine will result in higher fuel consumption and road tax compared to smaller or more modern alternatives. Insurance groups for the 5 Series are typically mid-to-high, reflecting its executive status.
Maintenance costs for a BMW of this vintage can be significant, particularly for suspension and braking systems. Expect annual running costs to be elevated due to the combination of fuel, tax, and the need for preventative maintenance on a high-mileage chassis.
Prioritise the underbody and suspension. The MOT history flagged corroded brake pipes and worn anti-roll bar ball joints—the latter being a common failure point for this model according to aggregate data. Check for any remaining signs of rust on the chassis and brake lines.
Inspect the condition of the recently replaced front tyres to ensure they are of a quality brand. Additionally, check the headlamps and suspension arms, as these are identified as frequent failure points across the wider 523 dataset.
This grey BMW 523 has covered 147,563 miles, which is above the average for this model. The MOT history from July 2026 shows a failure involving brake pipe corrosion and worn anti-roll bar joints, though these were rectified for a subsequent pass. It is a high-mileage example of a 2.5L petrol executive saloon.
This model has an average MOT pass rate of 76.8%, with frequent failures linked to anti-roll bars and suspension arms.
