We have it, and have for years since they helped us with a rental car company problem. We reserved and rented a car from one of the BIG car rental agencies. We arranged through our phone reservation to drop the car at a second airport a week later. No problem when we made that reservation, no problem when we picked the car up...then when our credit card bill came they attempted add a charge for the drop elsewhere, a HUGE, HUGE fee -- around $1,500 claiming that they could find no record of the second drop reservation. No matter what we did the rental agency was not going to drop that charge. Hubby got the idea to call AAA to ask for advice. Although we didn't make our reservations through AAA guess what, they got involved and the rental company backed off completely and dropped the extra charge! This one "complimentary" service by AAA has paid for their membership fees many many times over.
We booked a trip to Hawaii through them and that was wonderful, and we saved quite a bit.
When our daughter was a teenager she ran out of gas on the freeway while her dad and I were out of town. AAA took care of her quickly. Also, we've had to be towed on a couple of occasions and AAA has always served well.
For those reasons we continue to keep their service and do recommend them.
