The Federal 4 was purchased in 2018 and quickly became one of the most popular shuttle buses due to its size. However, after the pandemic in 2020, the shuttles were mostly unused and began to incur more costs than they generated. In March 2025, a decision was made to transform this bus into a party bus, and the result is fantastic. The Fed 4 now features 16 seats with seat belts, ample cup holders, a lighted floor, a TV, and a Bluetooth stereo with a DVD player. It has since become one of our best party buses.
