The vehicle holds a valid MOT certificate following the September 2025 test at 18,730 miles, which remains current as of June 2026, with the overall roadworthiness status stable across the recorded history. The tester recorded a single minor advisory regarding slight damage, cracking, or perishing across all four 245/50R19 tyres, which aligns with standard rubber degradation rather than an acute mechanical failure. Previous records show a completely clean pass in September 2024 at 14,647 miles, indicating that core safety systems including brakes, steering geometry, and structural integrity passed without note. The maintenance trend shows consistent compliance with annual testing requirements, though the emergence of widespread tyre perishing suggests prolonged static storage or infrequent driving cycles rather than active neglect. At roughly 3,746 miles per annum over five years, the odometer reading reflects exceptionally light usage for a diesel SUV of this specification. The exact twelve-month interval between both recorded tests eliminates any suspicion of delayed inspections or rapid mileage accumulation. Low annual mileage often preserves drivetrain components but accelerates rubber and plastic deterioration when vehicles sit stationary for extended periods. The absence of advisories in the 2024 test followed by uniform tyre degradation in 2025 points to environmental exposure or lack of regular load-bearing runs rather than mechanical abuse. Owners typically experience hardened sidewalls and micro-cracking when modern performance compounds remain unloaded below their optimal operating temperature range. A prospective buyer should verify the current tread depth and sidewall integrity of all four wheels before committing, as perished rubber compromises wet grip and increases puncture vulnerability regardless of remaining groove measurement. Inspect the front and rear coil springs for stress fractures and check suspension bushes for dry rot, since low-mileage diesels frequently develop stiff mounts from infrequent thermal cycling. Examine the brake discs for surface corrosion and test the caliper pistons for smooth retraction, as standing periods commonly cause initial rotor pitting and binding pads. Verify the exhaust system for internal condensation residue and confirm the AdBlue tank operation, given the mild-hybrid diesel architecture requires regular highway running to maintain emission control efficiency.
