Limousines

It is simpler to determine the effects of altering a separate chassis than it is to determine the effects of altering a load-bearing unitized platform body. Coach builders have built models based on SUVs with a separate load-bearing chassis.
Stage
Another type of vehicle modified for multiple passenger use is the motorized stage, applied to the same tasks as the earlier stagecoach. It is not considered a true limousine but rather in its design and application is between a sedan and a bus. While a bus will have a central interior aisle for access to seating, a stage has multiple doors that allow access to transverse forward facing seats. Examples of the type were constructed not only from sedans (e.g., Chrysler New Yorker, Cadillac DeVille), but also from station wagons; many of the station wagon conversions sported a large rack, running the length of the roof, for carrying the passengers' baggage.
