my wifes car is a 02 mitsubishi dilemma with low mileage and in good nick but it recently failed the nct on emmissions - the cat convertor needs to be replaced and its proving very difficult to get a second hand replacement through breakers leaving the option to put a new one into it which would cost the bones of a grand.........not worth doing that, car itself is only worth €1500 maybe and its a shame to scrap it as its in great nick. she only goes up and down the airport to work so i guess the short journeys didnt help the build up in the cat..any ideas? cant really afford to replace it just now bit of a catch 22
