It depends on the area you live in (cities) and how busy they are, to what service you get. It's like everything, supply and demand.
We have had 10 "AA tow in's" in the last 8 working days, most people were not happy with how long they had to wait/ the way they were towed in etc.
Now "AA" fix 8/9 out of 10 (I can remember what they quote) cars on the side of the road/house etc, so in real numbers that means they fixed either 80 or 90 other cars that we didn't see in our 30 mile radius (in the country) that we have to cover. (We don't belive there numbers).
So I'm sorry we don't rate them great.
