The Toyota Celica is a two-door coupe that first appeared in 1971 and spans seven generations up to 2006. The car was conceived out of a desire to compete with other "pony" cars of the day, such as the Ford Mustang. The first generation looked a lot like the Mustang, coming in hatchback and notchback body styles, and from 1978 to 1999, the car was customized into a convertible. The Celica came in many variants across different markets. North America would see the ST, GT, GTA, GTS, and GT-Four (Turbo-All trac). The rest of the world received similar cars but sometimes with different names, such as the SSII and VVT-i. Throughout its life, the Celica was powered by various lively four-cylinder engines and began using rear-wheel drive, but by 1985, it followed the trend of front-wheel drive vehicles. Toyota created something special for the fourth-generation lineup with the creation of GT-Four (Turbo-All trac). These four-wheel-drive cars made formidable rally participants and lasted until the sixth generation ended in 1999. The seventh generation of Celica ended in 2006.
