A T-Top is a type of car roof design that features a removable panel in the center, creating a distinctive "T" shape when viewed from above. This design allows for an open-air driving experience while maintaining structural integrity. T-Tops were popular in the late 1970s and 1980s, especially in sports cars like the Chevrolet Corvette and Pontiac Firebird. The T-Top design typically consists of two fixed side windows and a central section that can be removed. This feature provides a balance between the benefits of a convertible and the sturdiness of a hardtop. T-Tops are often associated with a sporty aesthetic and are sought after by car enthusiasts.
