So moral of the story is, have AAA or a similar service so you don't have to keep all the parts to rebuild your motor in the trunk causing premature wear on suspension, tires, and tranny from all the weight.
After all, if you are driving home at 2 in the morning and drive by a semi that just hit some nuclear radiated super coon that is so big it tears up your hoses, dents your radiator, and put a hole in the pan... we want the tools to repair your car instead of calling AAA or just easing it home... right?
