Excellent advice, thanks all around. Just to be clear, the main purpose of keeping an extinguisher in my car is to put out small incidental fires rather than putting out one that has started in the engine of my car or whatnot (I know when to back off <img src="/images/graemlins/tongue.gif" alt="" />). More of a in case of emergancy situation where someone has caught fire for whatever reason or the small fires that can ocur when BBQing or tinkering with junkers.
