Literally nothing at all I have a BMW but I would rather have a car with good gas milage tbh. Like a 2011 Hybrid Toyota Camery w/ navigation would just be perfect. That's about as far as my knowledge of cars goes
No dad taught me, so everything I learned about vehicles I learned in trucking school. Automatic transmission vs. Manual transmission. your fluids: Oil, coolant, windshield wiper fluid, diesel levels, DEF (Diesel Exhaust Fluid) levels, air brakes, torque rods, suspension system, air pressure for tires, making sure all the lights are working...all that pre-trip and post-trip stuff before and after a long day of driving.
DOT (department of transportation) in all states are extra anal when it comes to truckers. We have to constantly make sure all that stuff works. they will give you a ticket for ANY little thing they find. They know our license IS our livelihood and if that gets suspended....
