The Detroit Autorama has been put together in-collaboration between the Michigan Hot Rod Association (MHRA) and Championship Auto Shows (CASI) since 1961. In 1963, CASI President Bob Larivee Sr. helped the Michigan Hot Rod Association (MHRA) form a new governing body for show car events, titled the International Show Car Association (ISCA). The ISCA has since become the leading promoter and governing body of show car events and competitions in the country. Along with CASI (now "North America's largest producer of indoor hot rod shows") they co-promote and judge events from coast-to-coast, ranging from the Boston World of Wheels to the Grand National Roadster Show in Pomona, California. All ISCA events have a series of "Outstanding Awards" for more than three-dozen classes. Each one counts as a single point in the ISCA point standings, which is split into four overall classes: Rod, Custom, Truck, and Bike. If at the end of a season, a single contributor has four Outstanding Awards in a single category, they are locked-into the ISCA Championship Finals, which is held every as part of the Chicago World of Wheels, the week following the show at Cobo. Many Ridler Winners and Great-8 cars have gone-on to attend other ISCA shows and win an overall Class Championship. Most recently Tammy Ray and her '34 "Gold Digger" did so in back-to-back seasons in 2010 & 2011.
