“On a rainy night, jan 10, 2014, I came out of work and started my car. I thanked god it started because sometimes it wouldn't start at all. Even after replacing almost every engine part including the computer. I started driving out of the parking spot and I smelled something burning inside the car. The engine started revving wildly up and down. I had no control of the car. White thick smoke filled the car fast. Flames started shooting out at me from under the dashboard. I was so panicked that I could hardly get out of the car. The insurance co totaled it and I still owe 500.00! …”
