Cars can come in a large variety of different body styles. Some are still in production, while others are of historical interest only. These styles are largely (though not completely) independent of a car's classification in terms of price, size and intended broad market; the same car model might be available in multiple body styles (or model ranges).
Please note that while each body style has a historical and technical definition, in common usage such definitions are often blurred. Over time, the common usage of each term evolves. For example, people often call 4-passenger sport coupes a 'sports car', while purists will insist that a sports car by definition is limited to two-place vehicles.
