Phoenix Airport Taxi

Traditionally, the limousine has been an extension of a large sedan. A longer frame and wheelbase allow the rear passenger compartment to contain the usual forward facing passenger seat but with a substantial amount of footroom — more than is actually needed. Usually then two "jump seats" are mounted, facing rearward behind the driver. These seats fold up when not in use. In this way, up to five persons can be carried in the aft compartment in comfort, and up to two additional persons carried in the driver's compartment, for a total capacity of seven passengers in addition to the driver. This type of seat configuration has however become less popular in recent limousines.

This type of vehicle was once rather common in some locations. An example of its use was in the transport of travelers arriving by railroad at Merced, California to Glacier National Park and Yosemite National Park in the first half of the 20th century. In Glacier National Park, these were referred to as "Jammers" in reference to the nickname of their gear-jamming drivers. In Yosemite, passengers would then stay in rustic platform tent camps or more expensive lodges (both of which are still available) and hike or rent bicycles for movement around the park.
