2025 BYD Sealion 7 Comfort EV Electric · WD75 VTY

The vehicle currently has no recorded MOT history, which is entirely expected given its age as a 2025 model. In the United Kingdom, new vehicles are exempt from MOT testing until they reach their third anniversary. Consequently, it is impossible to establish a maintenance trend or identify historical failure points through official DVSA records. The buyer must instead rely on a thorough physical inspection and a rigorous review of the manufacturer's service records to ensure the vehicle has been maintained according to the prescribed schedule. Due to the lack of sufficient mileage data, it is not possible to calculate an annual usage rate or determine if the vehicle has been driven extensively or has remained largely stationary. This lack of context is a critical consideration during a test drive. If the vehicle has been used sparingly, there is a risk of component stagnation, whereas high mileage would necessitate a closer look at the wear on suspension bushes, coil springs, and tyre tread depth. Without a mileage history to compare against the age, the buyer must verify the odometer reading against any available service stamps to ensure consistency and prevent odometer tampering. As there are no recorded advisories or defects to investigate, the inspection should focus on age-related degradation and potential issues stemming from infrequent use. Examine the tyres thoroughly for any signs of sidewall cracking or perishing, which can occur regardless of tread depth if the vehicle has been parked for long periods. Check the brake discs for excessive surface corrosion or pitting and listen for any signs of binding calipers or uneven braking, which can result from moisture buildup on the rotors. On a test drive, pay close attention to any unusual clunks or knocks from the suspension, as these could indicate premature wear or loose components. For an electric vehicle of this vintage, it is also essential to inspect the underbody for any signs of impact damage that could compromise the battery casing or high-voltage cabling. Verify the health of the 12V auxiliary battery, as these can lose charge if the vehicle is not used regularly, potentially causing electrical system failures. Finally, ensure that all manufacturer-mandated inspections, including brake fluid moisture checks and software updates, have been documented in the service book to confirm the vehicle's long-term reliability and structural integrity.
