What this means if you are buying one

This model year fails more often than most cars its age, so budget for repairs and check the history carefully. Before buying, check the area that fails most: catalyst emissions: carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits. Then look up the car's own MOT history on GOV.UK with its number plate, and look for repeat advisories.
