You need to get the car in the garage and tear every body panel off that car and become familiar with the car. Understand the chassis, the wiring, the cables, the brakes, etc. You should be able to sit in that car with your eyes closed and know where every switch is at, where every shut off is at and be able to get out of that car in case of an accident. Put yourself in the scenarios and do drills that make this a reaction and not a panic if something happens.
