Haha dw! We all start somewhere xD

Drivetrain refers to things such as the gearbox, mostly, but can include other related stuff that includes the axle shafts that connect to each wheel (in your case, two axle shafts to your front wheels because it’s a front wheel drive car), the CV joints and boots (the little boots at the end of each axle that contain the grease that keeps the joints that connect to the wheels to keep them lubricated) it’s basically what interacts with your powertrain (engine) to move your car!

Check for rust, brakes and drivetrain…just to be safe
