Hey, im kinda young and i have a while to go untill i get a car and my licence, but next year is highschool and im taking automotives class and i want to be a mechanic, so im reading as much as i can.

OK to start off the engine drives the cars and gas drives the engine and people can sit in the car and drive the car with the engine ect ect
