Cleveland Auto Show moves downtown, plans 2021 event for December Cleveland Auto Show A crowd gathers at the 2019 Cleveland Auto Show at the I-X Center. The long-running show is moving downtown this year in the wake of I-X Center's closure. The 10-day event is set for Dec. 3-12 at the Huntington Convention Center of Cleveland. The 2021 Cleveland Auto Show, in limbo since the I-X Center exited the event business, is moving downtown. The Greater Cleveland Automobile Dealers' Association confirmed Tuesday, Feb. 2, that the show will be staged at the Huntington Convention Center of Cleveland from Dec. 3 to Dec. 12. Those dates are a significant shift for the long-running show, which traditionally takes place in late February and early March, serving as the kickoff to the spring car-sales season.
