It would be cool to see the mechanics take apart the police car and explain how the car is put all together. The crown victoria police cruiser is quite cool to see but the back seats are rough. I have been in the back of those seats for a ride a long and its uncomfortable.
A vehicle is a drivers responsibility. Basic maintenance should be done in order to ensure its safety and performance. If a specific problems may arise due to engine failure then it is beyond the drivers capacity to solve it. As such expert mechanics should be called and required maintenance checkup should be made. A legitimate shop must be called in to do maintenance and repair.
