I can't speak too much of American AAA, but if it's similar to Canada's CAA, I think it's a good deal. It's saved my behind on a couple occasions with older vehicles. It also provides some pretty substantial discounts at certain shops, particularly automotive shops. One can also get some pretty cheap insurance up here if one's a member. Up here, if one fills at Husky or Mohawk, one earns points that can go to reducing the cost of the annual membership. A few years back, I did so much driving my top end membership cost under $10.
I know that manufacturers' roadside assistance programs have really cut into the business of AAA and CAA, but they still have their use. Most roadside assistance programs do expire, unless you drive something like a Benz, anyhow.
What would AAA run you, out of curiosity? My CAA is close to $90 a year, I think. That's the top end package that allows for relatively lengthy tows, since I do spend a fair bit of time on the highway.
