A Toyota drove right into the window of the Columbia Ford dealership on Route 6 in Columbia just before 11 a.m. on Tuesday.
Neither the woman who was driving nor anyone else was hurt and the car has since been removed from the building, police said.
The crash happened in the area where the Thunderbird Café is located.
According to the dealership, the woman bought the car last month and was there to pick up her second key when the accident happened.
The dealership and cafe inside are open, according to an e-mail from Columbia Ford.
