Yep! I've got extinguishers in my Austin and the Camaro. I've used the one in the Camaro, but on somebody's car who didn't have an extinguisher! When I put out the fire in a neat old '55 Ford the lady driving looked at the mess and said, "My husband is gonna be mad about that mess!"Hahaha yup, I learned that lesson a long time ago always keep a fire extinguisher in your car. The car was on fire from all the hot transfluid sprayed everywhere.
