What this means if you are buying one

This model year is about as good as an average car its age. 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.
