You will be eternally frustrated with cars without a few simple tools that cost <$10 total. To repeat and add to above, I carry in all my gas cars: in-line spark tester, jumper wires, multi-meter, starter fluid. In my classic cars, I also carry a backup spark box, electric fuel pump, and carburetor (ones w/ EFI). This has made my life simple and gotten me back on the road or out of the garage quickly. In my dumF kid days, I was helpless and often frustrated, and cars in the 70-80's were more problematic, IMHO.
