A limousine (or limo) is a luxury sedan or saloon car, especially one with a lengthened wheelbase or driven by a chauffeur. The chassis of a limousine may have been extended by the manufacturer or by an independent coach builder. These are referred to as “stretch” limousines and are traditionally black or white in color. Limousines are often driven by chauffeurs and until the mid-1990s were most often associated with the wealthy. They are also used for special occasions such as weddings, parties and sight-seeing tours.
