for more videos from the 2010 SEMA Show. From million-dollar supercars to classic hot rods, aftermarket automotive parts like tires, exhausts and superchargers are big business, in some cases bigger than new cars. At this year's annual Specialty Equipment Market Association (SEMA) auto parts makers unveiled the latest in new designs, technologies and accessories. Camaro was named the "Hottest Car" at the show for its accessory-friendly old and new models that give drivers more options for personalizing their car. Some of these options include high-end graphics, original wrap details and a first-of-its-kind emissions compliant engine. The LS3 E-Rod was one in a line of ground-breaking "green" engines that replace or improve the engines of classic cars.
