you are so predictible. i knew out of my post the thing you would pick up on is the wiper blades. that was an example you fool. let's use another - brakes. if you need new brakes the £250 service plan will not cover it. is that clear enough for you?
Have you just passed your test?
Is this your first car?
Are you really that naive?
Brakes are consumables...like tyres, or wiper blades - the harder/more you use them, the faster you wear them out.
Services don't cover them...that's what maintenance plans are for. Is that clear enough for you to grasp?
They never have and never will.
