MOT Roadworthiness: Excellent

Our Verdict
Proceed with caution – the lack of any M
Ask the seller for any service records, battery health reports, and evidence of road tax exemption, as these are not captured in MOT data. Verify that the vehicle has a valid UK registration and that any required inspections for electric vehicles (e.g., high‑voltage system checks) have been performed. Negotiate a price that reflects the uncertainty around the missing MOT and mileage data, and consider obtaining a professional mechanical inspection.
The BYD Dolphin is still early in its lifecycle, so warranty coverage may still be in effect. Confirm the remaining warranty period and whether it is transferable. If the warranty is still active, request documentation of any warranty claims or repairs to gauge potential recurring issues. Also, check the condition of the charging port and cable, as wear here can be costly to replace.
Be aware that electric vehicles can have specific concerns such as battery degradation and software updates. While the model’s average MOT pass rate is 84.2%, this figure includes a range of issues from minor advisory notes to more serious failures. Look for any recorded advisory items in the MOT history of similar vehicles, even if this specific car lacks a record, to inform your expectations.
Fuel costs for an electric vehicle of this size typically run between £300 and £400 per year, assuming average UK electricity rates and the model's estimated range. Road tax is currently zero for EVs, which helps keep running costs low.
Insurance groups for the BYD Dolphin Comfort EV generally fall in the mid‑teens (around group 15‑18), leading to annual premiums of roughly £500‑£700 depending on driver profile. Maintenance on electric cars is usually lower than on ICE models, with typical annual servicing and tyre wear costing around £200‑£300.
Putting these figures together, a reasonable estimate for total annual running costs is between £800 and £1,000, covering electricity, insurance, tax exemption, and routine maintenance.
Given the absence of MOT data, start by checking the vehicle's lights, indicators, and brake performance, as these are common MOT items. Verify that all exterior lights function correctly and that the brake pads and discs show adequate wear.
Inspect the high‑voltage battery and its cooling system for any signs of damage, swelling, or corrosion. Look for any warning lights on the dashboard related to battery health or electric drivetrain faults, and request a battery health report if possible.
Examine the interior for wear on the charging port, ensure the cable connects securely, and test the vehicle's onboard charging system by plugging it into a known good charger. Also, check the suspension and steering components for any noises or play, as these can be flagged in MOTs for older vehicles but may still be relevant here.
The 2025 BYD Dolphin Comfort EV (registration YO74SBV) is a relatively new electric vehicle with a grey finish. No MOT history is available, so its compliance and any past failures cannot be confirmed. Model‑wide data shows an 84.2% MOT pass rate, indicating that some owners experience failures. Without mileage information, assessing wear is difficult, so a detailed check is essential before purchase.
Across 4,059 BYD Dolphin units, the average MOT pass rate of 84.2% indicates a moderate level of reliability, with a proportion of vehicles experiencing failures or advisories.
