Most used car warranties do not cover wear and tear so bushes rusty pipes etc wouldnt be covered, a warranty is for mechanical or electrical failure. Also a warranty company will not pay out for a fault that was present at the point of sale. A used car is a used car at the end of the day, if its road worthy then that in my eyes is fair, it will have worn parts on it as its not a new car. I do agree with whoever it was that said about free health checks etc as they do them to get further work, they don't just do them to just help us folk with how good or bad our cars are.
