Blas,
I didn't do mine because I thought it had to be or for legal reasons. I just did it to satisfy myself. I try to be extra careful when dealing with gasoline or anything that could cause a fire or explosion. True, I have only seen one car catch fire from a static charge and it wasn't a Cobra but a Chevy. But I also had more ground straps than most people use. My battery was in the trunk and I had a short ground strap from it to the frame. Then I had two big ground straps from the block to the frame. I then took a terminal strip and mounted it to a place I could get to easily and grounded it to the frame. That way if I needed a ground for something I could just go to that terminal strip and use one of the terminals. Just my being Paranoid I guess and overdoing the safety stuff.
