The recorded mileage of 79,849 miles is high for a 2020 model, averaging approximately 13,308 miles per year. This indicates heavy usage over its six-year lifespan. The MOT history is sparse, providing only two data points, but these entries show a consistent testing pattern without intervening failures. A physical inspection should prioritise high-wear components typical of high-mileage vehicles. The buyer should examine the suspension bushes and coil springs for signs of fatigue. Brake discs and pads require scrutiny to determine remaining thickness, as these consumables wear faster under heavy use. Checking the drivetrain and exhaust system for leaks or corrosion will provide a more complete picture of the vehicle's current state.
