The Autorama is produced (bankrolled and much more) by Championship Auto Shows, which has an entire circuit of top quality indoor shows across the country. The Michigan Hot Rod Association runs the show, organizes it, takes care all of the set up and judging, for starters. They started the show as way to raise funds to build a drag strip in the '50s. MHRA is closed association of 7 clubs, going back to the beginning of MHRA.
The Hall D (basement) show is called Autorama Extreme- and is for traditional, old school, and radical build (often unfinished looking) hot rods and customs. It is NOT really a “rat rod” show any longer. The non-driving channeled Model A shown, is just a liquor company promotion and is NOT typical of the cars in the show. There are many cars there, that could easily be competitive upstairs, but the owners prefer the ambiance and thrust in the Extreme.
*With over 500 cars on exhibit, there is something there for everyone, of all ages to enjoy. It is the best value in a large car show!
