exactly what engine is it, im assuming the 1.3 cvh, or is it the ohv?
also, does it have typical headgasket symptoms, what exactly has happened?
at your age, insurance will b bad, especially on a converted car, which makes it a percentage worse
i did mine when at uni, and even just the increase in fuel usage killed me, let alone the constant problems and money needed to fix them and keep it roadworthy. and that was when i had money coming in from part time work, plus threw all my student loan at it lol
