My parents have used AAA (Automobile Association of America) for many years for their roadside assistance service. Last year (2008) they used their service to tow my car to my mechanic even though I wasn't on their policy. I decided at that time that I needed a policy of my own.
I was extremely impressed with their inexpensive coverage and trouble-free service. The tow truck arrived in about a half an hour, the driver was professional and courteous. I couldn't have been more pleased with the tow service AND with AAA.
The AAA operator handled the situation very well. I was pretty upset at the time, feeling helpless and concerned with how much the repair would cost to get my car back on the road. The operator I spoke with was very kind and considerate.
I couldn't have asked for a better experience and highly recommend AAA.
The garage that worked on my car, that's a whole 'nother story!
