2007 BMW 730 3.0L Diesel · NJ57 CAX

The latest MOT test conducted on 11 April 2025 resulted in a pass with no recorded defects. Reviewing the historical data, the vehicle has experienced failures in both 2023 and 2024, though these were followed by successful retests. This indicates a maintenance trend that is currently stable, where any identified faults appear to be addressed to maintain roadworthiness. The transition from failures to consecutive clean passes suggests that the vehicle is being monitored and maintained to meet regulatory standards. With a recorded mileage of 92,064 over 19 years, the vehicle averages roughly 4,845 miles per year. This is considered low usage for a premium saloon of this age. While this suggests lower cumulative wear on the engine, gearbox, and drivetrain, such low annual mileage can often imply the vehicle has spent significant time stationary. This usage profile shifts the mechanical concern from high-mileage wear to age-related degradation of rubber, seals, and fluids, which can be more insidious than traditional mechanical fatigue. During your inspection, you must look beyond tread depth and examine the tyres for signs of perishing or sidewall cracking, which is common in low-use vehicles. Check for any uneven wear patterns that might suggest worn suspension bushes or incorrect tracking. On the test drive, listen for clunks from the suspension or a shudder through the brake pedal, which could indicate binding calipers or corroded brake discs caused by infrequent use. It is also vital to check the condition of the 12V battery and ensure the vehicle starts promptly, as long periods of standing can lead to battery sulphation. Inspect the engine bay for signs of fluid leaks from aged seals and check the condition of coolant hoses and drive belts for cracking. Because maintenance on low-mileage cars should be time-based rather than mileage-based, verify that the service book shows regular oil and brake fluid changes regardless of the distance covered. Finally, inspect the underside for any signs of corrosion on the exhaust system or structural components, as moisture can cause oxidation to build up on stationary vehicles.
