2020 BMW 730 3.0L Diesel · YP20 VCJ

A single MOT failure on record, immediately followed by a clean pass the next day, points to a drivetrain rubber component that has since been rectified, with the rest of the test history showing consistent roadworthiness across three previous passes. The failure on 28 October 2025 was attributable solely to a split offside front drive shaft constant velocity boot, which would have permitted dirt ingress into the CV joint and likely resulted in accelerated wear of the joint internals if left unaddressed. The vehicle was re-presented and cleared with no defects on 29 October 2025, suggesting either a replacement gaiter or a renewed joint. Aside from this isolated failure, the 2024 testing pattern, comprising three passes in quick succession with no advisories whatsoever, demonstrates that the chassis, braking, suspension, and exhaust systems were in sound order at that point and have remained so. With 41,686 miles accumulated over six years, the car is averaging roughly 6,948 miles annually, a figure that aligns closely with typical usage for a luxury executive saloon of this type and indicates regular rather than sporadic driving. There are no significant gaps in the MOT history that would suggest extended periods off the road, and the mileage progression between tests appears consistent rather than erratic. This level of use is sufficient to keep drivetrain seals, brake components, and suspension linkages functional without subjecting them to the accelerated wear typical of high-mileage vehicles, though it does not eliminate the possibility of age-related deterioration of rubber and polymer components. For a prospective buyer, the principal area of focus should be the offside front drivetrain, specifically the CV joint that was exposed to contamination prior to the boot repair. On a test drive, listen for any clicking, knocking, or vibration emanating from the front of the vehicle during tight turns at low speed, as a damaged CV joint typically manifests as a rhythmic clicking that worsens under steering lock. Inspect the area beneath the car for any fresh oil or grease deposits around the offside front hub, which could indicate a perished joint seal or an incomplete repair, and check the gaiter itself for splits, perishing, or insecure clamping. Additionally, the advisories noted on the nearside tyres during the failed examination, including a sidewall damage mark on the front and a cut on the rear with reduced tread on the inner edge, warrant confirmation that matching tyres of correct specification and adequate tread depth are now fitted across both axles. The rear tyre advisory regarding inner-edge wear is worth particular attention, as uneven tyre wear can indicate misalignment of the rear suspension geometry, which on a 7 Series often relates to worn trailing arm bushes, thrust arm bush deterioration, or subframe mounting issues. During the test drive, pay attention to any pulling to one side under braking, any clonking or knocking over uneven road surfaces that might suggest worn rear bushings, and any vagueness or delay in steering response that could point to broader suspension compliance issues. Verify that all four tyres are of matching specification and that the rear pair show even wear across their width, as inconsistent patterns would suggest that further mechanical investigation of the rear suspension is warranted before purchase.
