Try and sell it for £1500 then it shows the others that you are trying to do something with it, then if it doesnt sell (having no mot and tax doesnt help as noone wants to pay a lot for a car without them) break it as you will probably get more for it that way like you say, advertise it on gumtree, its free and you can put it in loads of areas, and try friday ad or ebay?! Hope i havent been to unkind?!
