My answer to MOT`s, ...if we are dedicated enthusiasts we should know whether our our cars are roadworthy and or safe to drive, Checking most things from wipers to brakes should be the norm well before taking any Historic car on the road. Even with an MOT certificate in your hand , it can be nullified by a (rare) traffic cop coming along and checking your car over on a road side check. If he deems the car unsafe because he may pick up on something that he considers unsafe ...a piece of paper is useless. The modern MOT `engineer` nine times out of ten can get it wrong eg being told the wheel bearings are worn , when in most cases there is a tolerance of movement within the older unsealed bearings.or "there is no external rear view mirror, when prior to 1978 there was rule to say one should be fitted . I drive three MOT exempt cars and in each case know that that they are safe regarding road worthy-ness .....Now as for poor spares and replacements ...thats another argument
