AAA - used it for towing; I drive on long road trips often, so normally it's just a tire change that I don't want to do at 2am in the middle of nowhere, or a tow... Probably, over time, I've paid them more than I used them for, but it's great to have some number to call when you have auto problems and know someone will answer who will be able to help. For example, had a tire blow out outside of Las Cruces - I could have stayed on the I-10 at night and change it myself for the spare and maybe get hit by a car not noticing me on the small shoulder, or (what I did) call the 800 number and have a tow truck come out to help see how bad the damage was and eventually just helped me change the tire - but hey, a lot safer being in front of a huge tow truck than behind a small sedan at night.
