2020 BMW I3 Electricity · WD69 GFK

The 2020 BMW i3 presents a flawless MOT record across all four tests, with the most recent pass recorded on 8 September 2025 at 12,333 miles and zero defects flagged. The maintenance trend is entirely stable, showing no deterioration, recurring advisories, or emerging mechanical concerns over the vehicle’s life. For an electric vehicle, this is a strong indicator of consistent care and no hidden faults surfacing between annual inspections. The mileage accumulation is notably low. Between the December 2022 test at 5,392 miles and the September 2023 test at 6,882 miles, the car covered just 1,490 miles in nine months. The next interval, from September 2023 to September 2024, saw 2,907 miles added, and the most recent year to September 2025 added only 2,544 miles. At roughly 2,056 miles per year on average, this is well below typical annual usage for a six-year-old vehicle. Such light use can preserve consumables and structural components, but it also raises the possibility of long stationary periods, which can affect tyre flat-spotting, brake surface corrosion, and 12-volt battery health in electric vehicles. Despite the clean MOT history, a buyer should still carry out a physical inspection focused on areas that MOT tests do not fully assess. The BMW i3’s rear suspension trailing arms and subframe mounting points should be checked for corrosion, particularly given the vehicle’s lightweight construction and the potential for moisture ingress in rarely driven cars. Brake discs and pads may show surface corrosion from infrequent use rather than wear, which the MOT would not flag unless braking efficiency dropped below threshold. Tyre condition deserves close attention; low-mileage vehicles often have tyres that appear serviceable but may be approaching age-related deterioration, with sidewall cracking possible even where tread depth remains legal. The high-voltage battery health is another critical area that MOT records cannot reveal. A low-mileage electric vehicle can suffer from battery degradation if it has been left at extreme state-of-charge or exposed to prolonged high temperatures without use. Requesting a battery state-of-health report via BMW diagnostic software would provide far more meaningful data than the MOT history alone. Overall, the documented record is exceptionally clean, but the unusual usage pattern means a buyer should verify mechanical and electrical condition through independent inspection rather than relying solely on the pass certificates.
