2025 BYD Sealion 7 Comfort EV Electricity · AF75 OCR

As there is no MOT history recorded for this 2025 BYD SEALION 7 COMFORT EV, no official DVSA test outcome or trend can be evaluated at present. Vehicles typically do not require their first MOT test until they reach three years of age, meaning a 2025 model registered prior to September 2026 would only just be approaching its first roadworthiness examination around the date of this assessment. Consequently, no official advisories, failure points, or wear-based defect history are available to inform a mechanical trend, and any conclusion regarding the maintenance stability of this particular vehicle would be purely speculative. Mileage data has not been provided, which makes it impossible to calculate an annual usage rate or identify any periods of standing or rapid accumulation. Given the vehicle's registration year, the mileage should logically be relatively low, reflecting a near-new condition, but this cannot be confirmed without access to the odometer reading or service records. For an electric vehicle of this age, a low annual mileage is generally beneficial for components such as brake discs and pads, which suffer minimal wear due to regenerative braking, though it raises separate considerations regarding time-based degradation of other systems. In the absence of MOT data, a prospective buyer must place greater emphasis on a physical inspection and verification of the vehicle's documentation. The V5C logbook should be checked to confirm the registered keeper details and ensure the VIN matches the vehicle, while the service book or digital service history should be examined for any manufacturer-approved inspections, particularly regarding the high-voltage battery state of health and the 12V auxiliary battery, which can degrade from standing or infrequent use. The charging port, high-voltage cabling, and any associated warning messages on the infotainment system should be scrutinised, along with verification that any recalls or software updates issued by BYD have been completed and recorded by an authorised dealer. Given the low expected mileage and minimal wear, attention should focus on age-related and standing-related defects rather than mileage-related wear. Tyres should be inspected for sidewall perishing and cracking from age, even if tread depth appears adequate, and brake discs should be checked for surface corrosion or binding calipers resulting from prolonged standing. Although electric vehicles do not require traditional engine oil changes, the cabin filter, brake fluid, and coolant systems remain subject to calendar-based servicing intervals, so evidence of these being replaced in line with manufacturer schedules should be sought. A test drive should confirm smooth operation of the regenerative braking system, absence of suspension clonks over undulating surfaces, and proper function of all driver assistance and safety systems, while an underbody examination can identify any transport damage or early corrosion on structural components.
