Take the two couches in your living room and arrange them in tandem. Wrap them in three tons of sheet metal and place them on four wheels with tires. Add one huge engine and transmission and you have the ultimate road car...a 1959 Cadillac. This car was nearly 19 feet long, but it was like cruising down the interstate in your living room.
Of course, if you ever tried to pile your friends in the trunk of a car and sneak into the drive-in movies, this is the trunk you want to use. You could put half of your senior class in this thing.
