PRO MOVE
USING THIS SHEET
Top to bottom — never jump around. Bonnet (under hood) → wheels off the ground (tires, brakes, suspension) → lighting walkaround → road test if symptom-based. Every single point gets marked. Never skip something because "it looks OK." Take 30 seconds to confirm vs guess.
When you find a RED item: stop the vehicle from leaving and get a service advisor involved. Don\'t fix without authorization. When you find YELLOW: document for the customer to see — that\'s how you build trust + repeat work.
