I have had RAC cover for past 7 years, had to use them a few times and can only say I found them quick to come out and the guys very friendly and helpful.
The 26 year old Cossy alternator shit itself about 6 months ago and buggered the battery as well. The guy who came out didnt have a spare square post one but still managed to fit a round post one with some modification to get me home. He followed me and then once I had put the car back in the garage took his battery out again.He told me he will always try to get a car mobile again rather than just say it needs recovery. Top man in my opinion. New alternator and new battery fitted , no problems again.
