No car dealerships carry a 2014 Pontiac Trans Am as no such car was ever produced by General Motors. In 2002, General Motors ceased production of the Trans Am and discontinued the Pontiac brand itself in 2009.
Though Internet rumors persist about the potential resurrection of the Pontiac Firebird Trans Am, the Pontiac brand remained inactive in 2014, and no models of any kind were produced. The closest equivalent to the Trans Am that remains in production as of 2015 is the Chevrolet Camaro. The Firebird Trans Am and Camaro were once mechanical twins that both used General Motor's F-body platform during their mutual production runs. Some race car dealers may sell vehicles intended for use in the 2014 Trans Am racing series, but these cars have no relation to the Pontiac Trans Am.
