It seems it's making you unhappy rather than happy I think breaking it would be a good idea to, it's never going to end there is always something you want to do to it everyone's the same people get to a point where it's too much hassle and not enough fun. Seems to me like you havn't had enough reliable drive time to feel content with it, your mates can obviously see it's getting you down, always be a shame to sell but it's just the way it has to be sometimes, good luck either way Chris!
