Mid America Coach recommends buying a newer shuttle bus, ensuring it's equipped with an AC unit that exceeds anticipated use, and opting for a gasoline engine rather than diesel. As with any used vehicle, obtaining a history report is advisable.
Walk the interior floor of the shuttle bus to check for weak spots that indicate a possible leak. Shuttle buses typically use plywood flooring with undercoating. If the floor has become compromised, this can easily result in replacement costs of several thousand dollars, according to MidAmericaCoach.com.
Additionally, since rear heaters are most often positioned under the seats, heaters placed in the middle of the aisle suggest the bus may have been used in a parking lot application. The seats were likely turned around to increase marketability, and the bus may have undergone heavy commercial use.
