It was originally the trolley-replica and conventional bus production business of Chance Industries, Inc. In 1998, Chance Coach, Inc. was sold to American Capital Strategies, which rebranded the company as Optima Bus Corporation in 2003. American Capital subsequently sold Optima to North American Bus Industries, who closed the Kansas assembly plant on August 8, 2007, with production moved to their existing plant in Anniston, Alabama.

Historic
The Chance RT-52 was a front-engined small-sized transit bus built by Chance Coach, Inc. measuring 25 ft in length. It was primarily used as a shuttle bus, and normally carried 19 passengers. The maximum passenger capacity was 23 passengers. Powered by an inline 6-cylinder Cummins 6BTA5.9 turbo diesel engine displacing 5883 cc, coupled to an Allison MT643 manual transmission, its gross vehicle weight (GVW) was 24000 lb, its wheelbase was 170 in, and it was 96 in wide.

The RT-52 was used in the Wiki Wiki Shuttle route at Honolulu International Airport. The first wiki site, called WikiWikiWeb, was named by its programmer, Ward Cunningham, after this line of buses. The buses were also purchased by Pace, primarily for use in Niles, Illinois; all have now been retired, with the last one running service routes in May 2007.

Chance manufactured the Sunliner trams, an open-air towed tram used at various parks and zoos in the United States and Canada.
