Organizer and city councilman Terry Jordan said 46 cars were entered into the show, and he was pleased with the results.
"It went really well," he said.
Jordan said 30 trophies were awarded at the show, in nine different categories. All the money raised by the event will go toward the 2010 Steve McQueen Days, Jordan said.
Best in Show at the event went to Dick Brewer's 1934 Chevy Coupe. That car also received first place in the Street Rods category.
The award for longest distance traveled went to Frank Brown and his 2010 Camaro. That same car won first in the Modern category.
Tim Trimble's 1956 Corvette took first in the category for Corvettes.
Bob Newman took first place in the Vintage '30s and Older category with his 1931 Model A. In the '40s and '50s Modified class, Dan and Kay Robinson's 1955 Chevy Bel Air was the winner.
In the '30s and '40s Stock category, George Berkamp's 1940 Chevy took first. Dennis Forseman's 1970 Mustang won in the '60s and '70s Stock category.
Jordan said he appreciated area businesses that sponsored the car show.
Other events at Slater Fall Festival included a popsicle-eating contest, a parade, a talent show and a carnival. There were also numerous vendors selling food and trinkets along Main Street.
Slater Assistant City Administrator Gene Griffith said the festival as a whole was very successful.
"We think it went fabulous," he said.
A total of about 6,000 people attended from Thursday through Saturday, which is about 1,000 more than last year, Griffith said.
Besides the car show, another big draw at the festival was a semi trailer full of monitors where visitors could watch Missouri veterans' stories, some of which were recorded in Slater's own City Hall.
"The Hometown Heroes was a great attraction," Griffith said.
