Other terms for convertibles include cabriolet, cabrio, drop top, drophead coupé, open two-seater, open top, rag top, soft top, spider, and spyder. Consistency is rare about the current use of cabriolet in preference to convertible. The term cabriolet originated from a carriage cabriolet: "a light, two-wheeled, one-horse carriage with a folding top, capable of seating two persons", however, the term is also used to describe other convertibles.

In the United Kingdom, the historical term for a two-door convertible is drophead coupé, and a four-door convertible was called an all-weather tourer. Nowadays, these names are generally used only for period cars.

A car is a wheeled motor vehicle used for transportation. Most definitions of cars say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people rather than goods. Cars came into global use during the 20th century, and developed economies depend on them.

The first full-scale, self-propelled mechanical vehicle was released in 1769. It was a steam-powered tricycle that was used to haul cannons around town. (But, it weighed 8,000 pounds!)

The 1964 Pontiac GTO is widely regarded as the first “muscle car.” Pontiac owned the muscle scene in the early 1960s, but by 1968, that car had plenty of competition.

Only 11 prototypes of the Porsche 916 exist. It’s one of the rarest cars in the world, as it was soon replaced by the less expensive Porsche 911.

The ancient Greek poet Sotades (3rd century BCE) invented a form of Ionic meter called Sotadic or Sotadean verse, which is sometimes said to have been palindromic, but no examples survive, and the exact nature of the "reverse" readings is unclear.

A palindrome was found as a graffito at Herculaneum, a city buried by ash in 79 CE. This palindrome, called the Sator Square, consists of a sentence written in Latin: "Sator Arepo Tenet Opera Rotas" ("The sower Arepo holds with effort the wheels"). It is remarkable for the fact that the first letters of each word form the first word, the second letters form the second word, and so forth. Hence, it can be arranged into a word square that reads in four different ways: horizontally or vertically from either top left to bottom right or bottom right to top left. As such, they can be referred to as palindromatic.
