I am making a 3d game where a character washes a car. The only input I want from the player is to choose where the character washes next. What is the best way to make my character model move from point to point on the car with a single button press from the player? I also need the character to walk around the vehicle instead of trying to walk through it to get to the next destination when given another input.

To get around the car
with navigation
or
an easier way
with pathfollow

/// with a single button
After cleaning the front of the car
Mission 1 finished, mission 2 begins
example:

if clean_car_front == true:
     clean_car_side
