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: joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt. Then look up the car's own MOT history on GOV.UK with its number plate, and look for repeat advisories.
