2021 BMW I3 Electric · DP21 PXV

The 2021 BMW i3 presents a clean bill of health on its most recent MOT, conducted on 16 June 2026 at 21,176 miles. The tester recorded zero defects, advisories, or failures. This marks the third consecutive clean pass, following identical outcomes on 17 June 2025 at 16,608 miles and 30 May 2024 at 12,469 miles. The maintenance trend is stable and consistently strong. No recurring faults, emerging wear patterns, or structural concerns have surfaced across the entire recorded MOT history. The mileage profile tells an interesting story. Across roughly five years, the car has covered just 21,176 miles, averaging approximately 4,235 miles annually. That is notably low for a vehicle of this age. The intervals between tests show a steady and predictable accumulation pattern: 4,139 miles between May 2024 and June 2025, then 4,568 miles between June 2025 and June 2026. There are no alarming gaps or sudden spikes in usage. The data is sparse in the best possible sense, with no defects recorded at any point, but the low annual mileage does warrant attention to components that deteriorate through age and inactivity rather than use. Given the clean MOT record, there are no recurring mechanical or structural faults to flag. The BMW i3's electric drivetrain eliminates traditional engine and exhaust wear items, but a buyer should still inspect the condition of the 12-volt auxiliary battery, which can degrade on vehicles sitting for extended periods. The tyres deserve close scrutiny, as low-mileage cars often suffer from perishing and flat-spotting due to prolonged standing rather than tread wear. Check the sidewalls for date codes and cracking. The suspension bushes, coil springs, and dampers should be inspected for corrosion or deterioration, particularly if the vehicle has been stored outdoors. The regenerative braking system and conventional brake components, including calipers and discs, merit a physical check since electric vehicles can experience brake seizure from infrequent use. Underbody and sill condition should be examined for any signs of surface corrosion, though the i3's carbon-fibre-reinforced plastic body panels resist traditional steel rot. The clean MOT history strongly suggests diligent ownership, but a pre-purchase inspection remains sound practice on any low-mileage electric vehicle.
