Basically, my MOT is up in may, but i'd like to take my car for an MOT this afternoon (basically so that i can get the work done sooner, as im quite sure it'll fail).
But, once i have had it tested, does the MOT still run out in may, or does it become void upon failure?. Hmm.

. Number plate bulb and tyres are simple to do, never heard of a "locking device" on a track rod end or a balljoint - unless he means the nut is missing! Could also mean the split pin that goes through the castlated (sp?) nut, or sometimes they have a little round plate type thing that goes over the nut and is then held in place with a split pin.
