2014 BMW 420 2.0L Diesel · NK14 SVT

The vehicle is currently roadworthy, having passed its most recent MOT on 23 March 2026 at 124,754 miles. The maintenance trend appears stable, though the record shows a pattern of immediate re-testing following initial failures. In both March 2025 and March 2026, the car failed its first presentation but passed shortly thereafter after remedial work. This suggests the previous owners were reactive, addressing specific faults only when prompted by the tester rather than following a preventative maintenance schedule. The mileage profile is consistent with typical UK usage for a vehicle of this age, averaging approximately 10,400 miles per year. Between the May 2024 test at 107,887 miles and the March 2025 test at 116,990 miles, the car covered roughly 9,100 miles. A further 7,764 miles were recorded in the year leading up to the March 2026 test. This steady accumulation indicates regular use, which is generally beneficial for engine components and seals to prevent issues associated with long periods of standing. While the most recent pass recorded no advisories, the recurring failures in consecutive years necessitate a close physical inspection of high-wear areas. A buyer should examine the suspension bushes and control arms for perished rubber, as these are common points of failure on BMW models of this mileage. Given the age, checking the brake discs for thinning or uneven wear and inspecting the exhaust system for corrosion is also essential. The lack of structural corrosion advisories in the history suggests the chassis remains sound, but an underbody check should be performed to ensure no hidden rust has developed since the last test.
