I think a good inspection would reveal any problems, but my worry is that RAC or AA might provide a poor quality inspection. As I understand it, they have almost no liability if they miss things, or else they argue that the fault was not there at the time of the inspection, but materialised just after the car was purchased. (I have googled around and seen some appalling situations)
I am trying to find a way to get the car looked at by someone who I am sure is competent instead of the luck of the draw.
So, are you saying my rights will not change by having the car inspected first? I presume there is always some common law standard of reasonableness for the age and price of the car.
