2020 BMW 730 3.0L Diesel · YC70 ACX

The vehicle remains currently roadworthy, but the maintenance trend shows a shift toward reactive rather than proactive upkeep. While the recent test in January 2026 at 94,184 miles passed, the tester flagged a nearside rear tyre worn close to the legal limit with uneven edge wear. This follows a pattern established in January 2025 at 66,223 miles where both front outer tyres showed similar edge-related wear alongside thinning front brake pads. The mileage profile indicates a significant acceleration in usage over the last two years. Between September 2023 (33,353 miles) and January 2026 (94,184 miles), the car covered over 60,000 miles in just 28 months. This equates to approximately 25,000 miles per year, far exceeding the historical average of 15,697 miles for this vehicle. Such high-intensity usage places considerable stress on the complex drivetrain components, suspension bushings, and braking system compared to lower-mileage examples. A buyer must prioritize an inspection of the wheel alignment, as the recurring edge wear on multiple tyres across different axles in the 2025 and 2026 tests suggests persistent geometry issues or worn suspension components. Given the rapid mileage accumulation, the condition of the control arms and ball links should be verified for premature play. The braking system also requires a thorough check, as the previous advisory regarding thin pads in 2025 indicates the components are nearing the end of their service interval.
