I had RAC for the first 5 years of car ownership..
Mixed results really
I dropped them like a sack of poo, when my 1985 Maestro developed an over-rich mixture...
The patrol-man told me that it was because my engine was knackered !!
Not good as I was about to go to wales for a week.
I sorted it myself... it was a faulty fuel enrichment valve, that had a perished internal diaphragm
Now the AA, I had been with them for 15 years and they were spot on... every time
I am back with the RAC, as a free part of my car insurance package... but have not had to call them out yet...
Although looking at the insurance documentation, I don't think the breakdown cover provides much help anyway...
I can only be towed upto 10 miles !! - not good as I often work 60 miles away
Thank goodness, that I know my car pretty well, so that I can fix it myself!!
