A trailer carrying rare cars caught fire late Wednesday evening on Highway 66 in Verdigris.
It happened at about 11:30 p.m.
The company that owns the trailer was dropping off a classic race car to a buyer in Claremore.
The crew had unloaded a 1967 Pontiac GTO and a 1981 Toyota Land Cruiser in order to unload the car, when a generator on the trailer caught fire.
Firefighters were able to put out the fire quickly.
A 2008 Honda Civic that was still in the trailer was badly damaged.
No one was hurt.
