The listing indicates that the car has been garaged for 20 years and stored for the last 4, but serviced and regularly run. This suggests that it has been maintained to some degree, but not used consistently. The presence of service books with 14 stamps and MOT certificates implies a history of upkeep, however, the listing doesn't explicitly detail any significant cosmetic or mechanical issues, but the age and storage suggest there may be some wear. It also states 'Years MOT and recently serviced' which is positive, but without more detail, a 'Good' rating seems appropriate.
