About this car

The advertised mileage for this 2026 BYD Seal U Boost is 1,640 miles. At £27,990, it is advertised £1,421 above our estimated market asking price of £26,569. We use UK dealer asking prices, including 901 BYD Seal U listings, and account for the car’s age, mileage and specification. The asking price is now £1,300 lower than when we first recorded the advert 145 days ago. That history is worth bearing in mind when speaking to the dealer. It is advertised by Sinclair Group Mercedes-Benz Of Cardiff & Newport in Pontprennau.
