2026 BYD Sealion 7 Excellence EV AWD Electric · WD75 VGL

At the time of writing, the DVSA database holds no MOT test history for this vehicle. As a 2026 registered model, it would not normally be required to present for its first MOT until it reaches three years of age, meaning it is currently either pre-due or has only very recently become eligible for testing. Consequently, there is no pass-fail trajectory, advisory record, or historical defect pattern to evaluate. In the absence of MOT data, the maintenance trend must be regarded as unverified, and the prospective buyer should request any pre-delivery inspection records, warranty paperwork, and the manufacturer's build and service documentation to substantiate the vehicle's mechanical provenance from new. The recorded mileage is not available within the data provided, which prevents any meaningful comparison between annual usage and the vehicle's age. Even with the odometer reading unknown, a nearly new vehicle such as this would typically be expected to display very low mileage commensurate with its registration date. It is important to confirm the genuine current mileage through the dashboard and to satisfy yourself that the figures align with the service history stamps or digital records held by the franchised dealer or specialist EV technician. Any inconsistency, anomaly, or gap between the displayed mileage and the supporting paperwork should be treated as a significant concern, potentially indicative of clocked readings, missed servicing, or undisclosed prolonged periods of inactivity. Given the clean and essentially non-existent MOT history, the buyer must focus on age-appropriate and EV-specific physical checks rather than historical defect analysis. Although the vehicle is young, the tyres should still be carefully inspected for sidewall perishing or cracking from age, particularly if the car has stood unused for extended periods, as rubber compounds can deteriorate with calendar age regardless of tread depth. The brake discs and calipers, especially on an EV with regenerative braking, are prone to corrosion and binding from prolonged standing, so the wheels should be rotated by hand to confirm free movement and the discs examined for any surface rust pitting or uneven lipping. On the test drive, listen for any suspension clonks over uneven surfaces, feel for brake shudder or judder under pedal application, and verify smooth, vibration-free operation across the regenerative braking modes, which should engage progressively without harshness. Equally important for a battery electric vehicle are the high-voltage traction battery state of health, the 12V auxiliary battery condition, and the time-based servicing of brake fluid, coolant, and cabin filtration. A diagnostic scan via an EV-capable tool such as the BYD service interface or an independent specialist reader is strongly advised to confirm the state of health percentage of the traction pack and to verify that no fault codes are stored within the drivetrain, charging, or thermal management systems. The charge port and cabling should be examined for wear or contamination, and a live charging session attempted to confirm reliable handshake and expected charging rates. Finally, all fluids, including brake fluid which is hygroscopic and degrades with calendar age, should be checked for age and condition, while the service schedule stamps or digital service log must be thoroughly verified to confirm that the vehicle has been maintained strictly in accordance with BYD's prescribed intervals, thereby preserving both mechanical integrity and the residual manufacturer warranty.
