Description

The 15th Annual All Pontiac Car Show in Pontiac, Illinois is revving up for a double Centennial celebration! In 2026, both Route 66 and the Pontiac automobile brand mark 100 years—and this car show honors them both in one exciting weekend.

The main event takes place Sunday, September 20, 2026, with a full lineup of classic Pontiacs on display downtown. The festivities kick off the night before with the Summer Send-Off Concert and Cruise-In on Saturday evening at Humiston-Riverside Park.

This free, family-friendly event benefits the Pontiac-Oakland Automobile Museum and celebrates the deep connection between a legendary American road and a legendary American car.
