MOT isn't really the reason, I was thinking of selling anyways - I just don't fancy putting and unknown amount of possible £s into a car I don't want to keep. It shouldn't really fail on much imo, I haven't had a really good poke about but my guess is the most expensive things it'll need is two front tyres.
I think I was just annoyed earlier on today, I might get it tested and just go from there :/
