The term 'CAR CATEGORY' can be broken down into three distinct crossword solutions: USED (4 letters), SEDAN (5 letters), and MIDSIZE (7 letters). A USED car is a pre-owned vehicle that has been previously owned by another person. A SEDAN is a type of car that typically has four doors and a fixed roof, and is usually larger than a hatchback or coupe. MIDSIZE cars are larger than compact cars but smaller than full-size cars, and are often considered to be the most popular type of car.
