Car spontaneously caught on fire. Total loss. Drove car home from haircut appointment 5 to 10 minutes away. Parked car as normal and went inside. Within approximately 5 minutes loud knock on door “Your car is on fire!” I came out of my home and saw my car in driveway with fire erupting from engine area onto windshield, and through hole in middle of hood.
