Rachel Hachero, 17, apparently wanted a Nissan 350Z convertible. A car dealer said the teen came to the dealership but couldn't get approved by herself for the loan.
Lee County deputies say when her mother refused to co-sign for the car, Hachero pistol-whipped her mom and made her drive to the dealership to sign for the car.
"Extremely determined, especially for a 17-year-old, she was pretty persistent. Mom was in a hurry, said she just wanted to sign the paperwork and go," said car salesman Sean Bannigan.
Deputies say Hachero's mom was scared to call 911 and waited until the next day while her daughter was at school.
The mother hasn't pressed charges because she told authorities that her daughter is an honor student who has recently been accepted to several Ivy League colleges on scholarships.
