Limousine

From Memory Alpha, the free Star Trek reference.

A limousine is a fancier, and often longer, car used on Earth. It was often associated with class and elegance.

While in the Julian Bashir, Secret Agent holoprogram, Dr. Bashir was riding in a limousine when Odo knocked on the window to talk about a woman, Arissa. Bashir gave him some advice, and then rolled down the window to see Falcon standing there, with a gun. Odo stepped out of the car, and Falcon suggested that Bashir shouldn't stop to pick up hitch hikers. (DS9: "A Simple Investigation")
