Ok you part with your money and you expect 12 months 24/7 car breakdown cover in return right? Well it is worth while looking at some of the perks that these car breakdown cover providers offer to get you to sign up with them. Take the AA for example., if you become a member then have a members page that give you an idea of the benefits outside of the AA breakdown cover you will get if you join their service.
For example there is 10 % off Hertz rental, I presume this means when you are away from home, otherwise you would use your own car, especially if you now know you will get home if you breakdown. Then you can consider 60% off AA Auto Windscreens, virgin wine and some travel offers throughout and of course they will also want to sell you insurance with discount.
The RAC and Green Flag are a bit more shy with extra benefits you can get, or their websites do not make it easy to find out preferring to focus on the car breakdown cover angle.
