Anyone who has ever experienced a car fire will not hesitate to tell you to have an extinguisher handy. I had a 1970 Buick Estate Wagon that my Dad bought new. It must have had a fuel leak as it caught fire as we started it in a storage building one day. No extinguisher. It was amazing how fast that car burned to the ground. Still one of my worst days ever! I can tell you know that I have extinguishers in all of my vehicles. I go by the old saying "an ounce of prevention is worth a pound of cure"!
