An expensive car, especially one which serves as a status symbol. A suit covered anus typically will drive an alphanumeric. The term comes from the practice among most auto manufacturers of using alphanumeric designations on expensive car models, as opposed to the model names used for cheaper cars, e.g. Infiniti G35 vs. Nissan Altima, or Lexus ES 350 vs. Toyota Camry.
There's nothing like driving an alphanumeric to show people that you're a big shot.
