Automobiles' body styles are highly variable. Some body styles remain in production, while others become less common or obsolete. They may or may not correlate to a car's price, size or intended market classification. The same car model might be available in multiple body styles comprising a model range. Some distinctions, as with four-wheel drive vs. SUV models or minivan vs. MPV models, the distinction between body style and classification can be particularly narrow.

While body styles have historical and technical definitions, in common usage such definitions are broad and may be ambiguous. For example, one person may call a 4-passenger sport coupé a "sports car", while another may define a sports car strictly as a two-place vehicle.

Some non-English language terms are familiar from their use on imported vehicles in English-speaking nations even though the terms have not been adopted into English.

Car manufacturers sometimes invent names for the body styles of their cars for the purpose of differentiating themselves from other manufacturers. These names are often, but not always, adaptations of other words and terms. The body styles themselves correlate closely to those listed above.
