A kit car, also known as a "component car", is an automobile that is available as a set of parts that a manufacturer sells and the buyer then either assembles into a car themselves, or retains a third party to do part or all of the work on their behalf. Usually, many of the major mechanical systems such as the engine and transmission are sourced from donor vehicles or purchased from other vendors new. Kits vary in completeness ranging from as little as a book of plans to a complete set with all components included.

There is a sub-set of kit cars, commonly referred to as a "re-body" in which a commercially manufactured vehicle has a new (often fiberglass) body put on the running chassis. Most times, the existing drive gear and interior are retained. These kits require less technical knowledge from the builder and as the chassis and mechanical systems were designed, built and tested by a major automotive manufacturer can also lead to a much higher degree of safety and reliability.

The definition of a kit car usually indicates that a manufacturer constructs multiple kits of the same vehicle which they then in turn sell. This should not be confused with 'hand built cars' or 'Special' cars, which are typically built from scratch by an individual.

Kit may refer to:

Any collection of items or components needed for a specific purpose, especially for use by a workman, or personal effects packed for travelling, such as:

An automobile, autocar, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods.

The term motorcar has also been used in the context of electrified rail systems to denote a car which functions as a small locomotive but also provides space for passengers and baggage. These locomotive cars were often used on suburban routes by both interurban and intercity railroad systems.

There are approximately 600 million passenger cars worldwide (roughly one car per eleven people). Around the world, there were about 806 million cars and light trucks on the road in 2007; the engines of these burn over a billion cubic meters (260 billion US gallons) of petrol/gasoline and diesel fuel yearly. The numbers are increasing rapidly, especially in China and India.

Jean "Jeannot" Ragnotti (born 29 August 1945 in Pernes-les-Fontaines, Vaucluse), is a French former rally driver for Renault in the World Rally Championship.

Ranking among his achievements are his conquering of the Monte Carlo Rally in 1981, what was the first turbo victory in the history of the WRC, alongside compatriot Jean-Marc Andrié against the might of the ultimate four-wheel-drive upstart, the Audi Quattro. In the following season, he took his Renault 5 Turbo to victory at the Tour de Corse. The Maxi version of the same Renault 5 was to reign again on the asphalt stages of European rallying, when in 1985, Ragnotti claimed the Tour de Corse again with Group B rallying at its zenith; a win that came on debut of Renault 5 Maxi Turbo. The 1985 Rothmans Tour de Corse would also prove to be a tragic affair after the fatal crash of Attilio Bettega on SS4 (Zerubia) of the event.

In the 1990s, Ragnotti continued to drive for Renault, this time in their front-wheel drive Clio Maxi.
