2007 Jaguar XJ 4.2L Petrol · BK57 WTL

Structural corrosion and high-mileage wear define the mechanical profile of this Jaguar XJ, which accumulated a total of 180,083 miles by the time it passed its most recent MOT test on July 14, 2026. While the historical record shows multiple clean passes over the years, the latest inspection introduces critical advisories regarding a corroded rear subframe alongside perishing rubber on both front and rear tyres. Earlier tests also highlight a progression of mechanical flags, notably a 2023 advisory for a worn offside rear lower arm outer rose bush, a pitted front brake disc, and a greasy, corroded offside front brake pipe, as well as a severe 2020 failure involving missing road wheel fixings across multiple wheels and an excessively corroded brake line. Accumulating roughly 9,478 miles per year over its nineteen-year lifespan, the vehicle presents a standard annual mileage accrual pattern without prolonged periods of dormancy or excessive fleet-style accumulation. This steady usage means that mechanical wear has been distributed over time rather than compressed into short bursts, though the high absolute mileage places heavy demands on the entire drivetrain, suspension geometry, and rubber isolation components. Prospective buyers must view this high-mileage chassis as one that has naturally subjected its heavy aluminium and steel architecture to significant dynamic loads and environmental exposure. On the test drive, a thorough check of the suspension and braking systems is paramount to evaluate the components flagged in previous MOT records. Listen closely for clunks, thrumming, or knocking noises from the rear axle when navigating potholes or uneven road surfaces, which would confirm excessive play in the lower arm outer rose bushes. Pay careful attention to pedal feel during heavy braking to detect any judder or pulsing caused by the previously noted front brake disc scoring, and inspect the hydraulic lines for any fluid weeping around the front brake pipes. Finally, a physical inspection on a ramp is essential to assess the extent of the corrosion noted on the rear subframe during the latest 2026 test. Surface scale can often be remediated, but deep structural degradation on these complex assemblies requires careful scrutiny. Buyers should also inspect the inner and outer sidewalls of all four tyres for the cracking and perishing flagged by the examiner, budgeting for immediate replacement if the rubber degradation compromises structural integrity.
