This 1981 Checker Marathon is an actual retired taxi and still has the bulletproof mechanicals that made Checker famous. This vehicle left the factory with the Buick V6 engine and automatic transmission that powers it today. A well-known fixture on the Houston entertainment scene, the “Tapp’d out Taxi” has graced every type of event-from black-tie galas down to down-and-dirty tailgate parties. Always a crowd favorite, the car has a complete on-board draft beer dispensing system, which can serve six varieties of keg beer simultaneously. The most visible part of the system are the six professionally installed beer taps incorporated into the car’s trunk lid. The system is powered by three CO2 bottles with regulators, and keg taps and tap handles for a variety of brands are included.
