We have it, about $150 a year for me,wife,and daughter. It is good for any vehicle you are in. One call to a tow truck would pay for all three of our costs.
I have used it for a lock smith (remember Bob) and when the daughters car broke down we had it towed to a mechanic from her house.
Very well worth the price.

Edit:
I forgot to mention, we get great prices for plane tickets, rental cars, hotels, tickets for six flags. That alone more than paid for the cost of the service.
