To consider a car a ‘classic’, the car must be at least 20 years old. There are many organizations and clubs that have set different requirements and criteria before considering a car to be a classic. For instance, according to CCCA (Classic Car Club of America), a car must belong to an era between 1925 - 1948 before deeming it to be a classic. Similarly, the AACA (Antique Automobile Club of America) requires cars to age anywhere between 25 and 50 years to regard them as classics. Therefore, the AACA regards any car older than 50 as an 'antique'. Also, apart from age, one may also consider other factors before calling a car a 'classic'. For instance, you may regard a car as a classic in terms of its rarity, popularity, condition, and model quality. To conclude, age isn't the only criterion to categorize a car as a classic.
