Here is a list of the 2017 Nationals classes and the definitions for them. Classes are subject to change due to the number of entries. Show officials reserve the right to determine class. ALL cars must be driven into their assigned classes for Saturday & Sunday judging & ALL decisions are final. Please, no large displays around car, including trophies and mirrors. NO glass bottles or containers. For the Safety of guests, participants, and cars, Please we do not allow canopies, tents, or pop-up shades of any kind in all show areas. No truck or back-up vehicles of any kind allowed in any of the show areas. No golf carts allowed except those used by show staff. No scooters unless they are properly licensed. Absolutely, NO cooking will be allowed in all show areas. With respect to your fellow participants and spectators we ask that you do not move your cars from show fields on Sunday till after awards. We know everyone is anxious to leave or load cars on trailers but it would be a little nicer is everyone would stay parked till after awards. Due to tie breakers or Best of Show pick it may be to your advantage to stay put. The purpose of the Trans Am Nationals is to provide a forum for Firebird enthusiasts to meet, display their cars, share ideas, and to enjoy the camaraderie of fellow Pontiac F-body owners. ENJOY THE SHOW !
