What this means if you are buying one

This model year does better than most cars its age, so it is a reasonable used buy on MOT record alone. Before buying, check the area that fails most: component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength. Then look up the car's own MOT history on GOV.UK with its number plate, and look for repeat advisories.
