The 56-year-old great-grandmother was picked to buy a dollar used car that had been spruced up by Grand Junction, Colo., businessmen.
Herrera's co-workers say she deserves the car because she never complains about her many responsibilities.
She also lets the homeless sleep in her house when it's cold.
The owner of Integrity Auto Repair was behind the project and had to screen 135 recommendations.
Herrera says her old car was called "Scarface" because it was in such bad shape.
Now, she's driving a new-to-her 1992 Ford Crown Victoria.
