Is your car free of big scratches, hazed headlights, wheel damage, etc? If so, you are good to go, just give it a good cleaning and wax job, make sure the black rubber trim is black, clean the interior and make sure you have a nice fire extinguisher. (some shows require them) Pick your class, there is usually a choice, import, stock Mopar, special interest and have a good time. You can always do a set of custom wheels, some engine bay dress up, some interior mods. You are usually allowed 3 mods and still be considered stock.
